海外TECH	DEV Community	Change your approach to accessibilty and get a better developer experience (and create more accessible websites)	https://dev.to/elischei/change-your-approach-to-accessibilty-and-get-a-better-developer-experience-and-create-more-accessible-websites-b6b	Change your approach to accessibilty and get a better developer experience and create more accessible websites You have probably heard about web accessibility on more than one occasion especially if you work as a front end developer But a lot of front enders think that making their applications accessible is a hassle That s not because we don t care but because the approach to how we implement it is kind of backwards Typically the site is almost finished before someone suddenly showes up with the “accessibility check list and since we are not allowed to write every little thing all over again from the start we try to put some ARIA attributes on top of the stuff that are already built and hope for the best In this blogpost series I will cover the things you should know as a developer to make the web an accessible place for everyone and to create a better developer experience for yourself and others The complete blogpost series will consist of five blogpost In this first one I will give you an overview of web accessibility Why is it important what makes a web page in accessable and what are the things that we as developers should take into concideration when creating web applications Why is it important The internet is such a huge part of education commerce socializing and entertainment so it s important to make it accessible to create equal access and equal opportunity And if you chose not to you chose to actively exclude potential users customers What makes a web page in accessible When we talk about web accessibilty most of us think of blind people or maybe someone that can t use a mouse That s not wrong and they are an important target group but webiste accessibility is about more than supporting screen readers and tab navigation Have you ever tried to navigate a webpage and become lost or been unable to find what you were looking for Or maybe you started to fill out a form then you got interrupted by a phone call and afterwards you can t remember what the input field was supposed to contain and the error you get only says “There is an error in the form What about reading the content of a webpage on your phone outside in bright sunshine By creating an accessiblie web application we make the experience better for all users Users diversityThere are four categories of access impairments cognitive motor hearing and visual And for each of them the impairment can be situational temporary or permanent Lets look at some examples A very noisy environment can make it difficult to hear This is a situational hearing impairment Blindness is a permanent visual impairment Having difficulty reading on your phone because of bright light sunshine is situational and visual A broken arm can make it impossible to use a mouse This is a temporary motor impairment While being paralyzed is a permanent motor impairment Feeling a bit overwhelmed by all the possibilities and challenges we should try to meet in our web applications Don t worry someone else has done a lot of work for you and written down a wide range of recommendations for making web content more accessible These recomendations are called Web Content Accessibility Guidelines WCAG and we will take a look at them in the next section Take an “accessibility first approachIf you ve been working in tech for a while you might remember when “mobile first became a thing In the beginning a lot of people typically clients who didn t want to pay more to support multiple screen sizes was against it Why should we care about users who visited our site from a phone They can use a laptop It took some time but after a while everyone was expecting front end developers to create these amazing responsive web sites And today that is something as natural as having a website in the first place I think that it is the same thing with accessibility Everyone is starting to realise that it is important and that it will benefit everyone but it is not common to have a “accessibility firts approach yet But I m here to tell you that you as a developer should take this approach even though those around you are not there yet It will make your developer experience better if you have accessibility in the forefront of your mind from the start When you take that into concideration when deciding how to structure your code or how to solve a user interaction your creations will be accessible from the beginning And you dont have to go back and refactor or haphazardly put some ARIA attributes on top of it In the next blogposts in this series I will give you some practical examples but first lets take a look at the guidelines that exists Web Content Accessibility Guidelines WCAG The WCAG guidelines are created by The World Wide Web Consortium WC Web Accessibility Initiative WAI If you want to read more about the initiative you can find their website here We have allready covered that WCAG is a set of guidelines and resources that we can use to create more accessible websites WCAG is divided into four main principals they say that web content should be percivable operable understandable and robust From a high level this is what they cover PerceivableInformation should be presented in a way that all users can perceive This means that you should not rely only on one of the users senses OperableThe web is interactive and it is important that users can navigate click on buttons fill in information toggle hidden content etc all without realying on a mouse UnderstandableThe principle is about predictability simple language good help functionality RobustThe principal about robustness is mostly about the code The content should be accessible as technology evolves This includes for assistive technology In addition to guidelines WCAG also covers concrete examples of how to implement different types of content Levels of WCAGFor each of the main principals there are guidelines that are categorized into three levels A lowest AA mid range and AAA highest For some types of content it is not possible to achive level AAA complience so most sites should have level AA as their goal This blogpost is already getting to long and we have one more topic to cover so I won t go into more detail about WCAG for now If you want to learn more about WCAG take a look at the official site Accessible Rich Internet Applications ARIA As a developer you have probably encountered ARIA attributes before If you haven t used them when writing code yourself maybe you ve seen them in other peoples code or in code examples ARIA is a set of attributes we use to describe the intent of our code for screen readers and other assistant technology What is ARIAThe MDN Web Docs defines ARIA like this “Accessible Rich Internet Applications ARIA is a set of attributes that define ways to make web content and web applications especially those developed with JavaScript more accessible to people with disabilities As mentioned ARIA is a set of attributes you can use to add metadata to your html Lets look at an example lt button aria describedby myButtonDescription gt Click here lt button gt lt div id myButtonDescription gt When you click here will happen lt div gt In the example above the “aria describedby tells us or the assistance technology that the functionality of the button is described by the div that has id “myButtonDescription ARIA is a huge topic so I ve dedicated a whole blogpost to it part of this series If you want to learn more you should take a look at the MDN Web Docs or the Web Accessibility Initiative site SummaryYay you made it all through this text heavy introduction Or you just jumped here for the TL DR Thats ok too Lets summarize what you just learned Accessibility is about more than blind people and screen readers and making the web more accessible will benefit all users Access impairments can be categorized as cognitive motor hearing and visual and they can be situational temporary or permanent By taking av “accessibility first approach you will get a better developer experience and help create equal access and equal opportunity by makin the web accessible to all There are a lot of things to consider but luckily we have resources like WCAG and ARIA to help us create more accessible web applications Did you find this article usefull Follow me on twitter to be notified when I publish something new Also if you have any feedback or questions please let me know in the comments below Thank you for reading and happy coding Eli	2021-06-02 10:17:34
海外TECH	DEV Community	Top 30 Open Source And Paid React Charts + Examples	https://dev.to/flatlogic/top-30-open-source-and-paid-react-charts-examples-3ikg	Top Open Source And Paid React Charts ExamplesThe most evident outcome of the digital revolution or the third industrial revolution that began in the latter half of the th century is the amount of data that is collected and analyzed every day In the global IP traffic first exceeded one zettabyte a zettabyte is equivalent to bytes The common amount of digital data in the world was more than zettabyte as far back as in According to Cisco research it s expected zettabytes of traffic per year by These numbers impress That data includes videos pictures tweets emails messages Besides web apps collect data about users websites collect cookies marketing needs to understand the preferences and behavior of thousands of users businesses require numbers to develop a strategy and move forward And what to do with that all collected information Show it…But how The world came up with several ways of representing the data tables charts and graphs Whether you need to organize analyze identify a trend track the changes over time you can use all tools above Representing your data in the form of charts is a great way to convey information to users But the visualization of charts must be beautiful and insightful to users The modern design of apps has gone far beyond the standard flat visualization that was a decade ago The main requirement has stayed the same charts must be informative However chart forms and types vary a lot so you have control over user experience via the design you chose and you are expected to make a good decision about the way you represent the data otherwise you shouldn t wait for a high number of users Charts are the most common data visualization components of mobile and web applications One of the advantages of JavaScript frameworks like React is that it offers scalable and versatile components React is a great framework that lets developers build rich and high quality user interfaces easily so your users will love to use the app In the article we discuss what types of charts exist how users can interact with charts what functional opportunities every type of chart offers define the criteria for picking the right chart and look through the list of the best React charts examples and libraries Charts types and their features that may be usefulLet s start with a review of the most popular and well known chart types Pie chart Possible functionsDroll down an option when the individual slices can be clicked to expose more detailed data The slice can be drilled down to the next sub category of data Drill up give an option to return to the previous upper level of the data Select slice all slices have no selection by default This option allows the user to click on the slice and select it if there is no drill down opportunity by moving it apart from other slices or using special animation like a blackout of other slices Select multiple slices selection of multiple slices An additional useful option here is summing data attached to the slices When to useWhen you need to show relative proportions or percentages of a whole dataset When you want to show the general sense of the part to whole relationship in the data without the precise comparison of separate slices When not to useWhen you need to compare data in different slices across pies Line chart Possible featuresScroll back time change the displayed period to earlier without changing the period size Scroll forward time change the displayed period to later without changing the period size Change time unit of measurement choose different time aggregation units year day hour etc Select a point if you want to see the detailed information of a certain point on a line you can click on it or just move the cursor over it Multi axis allows configuring the chart for multiple Y axes each associated with one or more data series It s useful when you need to track the dynamic in different interrelated continuous values that have different units of measurement or range Zoom in zoom out an option to interact with an x axis and change the size of the period for a chart It allows viewing for a large period The data on the line chart modify according to the selected period When to useTo visualize trends in continuous data that change over some time If you want to display multiple series of data for the same timeline and see the difference in their dynamics When not to useIf the data contains different categories and their all must be displayed Bar chart Possible featuresPick variation of bar chart charts can be oriented vertically categories on X axis or horizontally categories on Y axis If we face long categories labels like the sample above it is a good idea to use a horizontal bar chart Select a label when clicking or hovering the label it reveals detailed information about the values for the label Multiple select click on labels to select multiple labels If selection also sums up the values of every label it s great Change cancel selection edit or cancel the selected period Positive and negative variations a chart with positive values that are above a mid point zero by default and negative values that are below the mid point They are most often painted with contrasting colors Scroll left or right top or down if a chart is inscribed in the frame this option allows to look through all labels Zoom in zoom out an option to fine tune chart appearance by changing its Y axis dimension and number of labels at one frame When to useIf you want to make a comparison of metric values across different subgroups of your data in other words if you work with categories When you want to show the changes over time in a dataset Stacked bar charts are helpful when you want to see the relationship of every stacked sub bars on the total amount and track their changes over time When not to useIf you have multiple data series that are independent and are not parts of the whole When categories have different measurement units Area chart Possible featuresSelect a point by clicking on a certain point within a chart you can see the precise values of all categories at this point Scroll change the display period to earlier later Zoom in out an option to make the period on the chart smaller bigger Positive and negative values when a chart allows to display negative values only uses for non stacked area charts under X axis When to useThis area chart gives you a quick comparison of the trend for several series over the timeWhen you need to see the magnitude of the trend for all series When there is a lot of points on the X axis When not to useWhen you have a lot of categories to compare with insignificant variations in values between them When you need a precise comparison of values for categories Composed combined chartIn most cases composed charts are a combination of a bar chart and line charts Possible featuresSelect a slice an option to select a certain point and see all values from all types of charts at that particular point When to useIf you need to compare values with different measurement units If the values are different in range When not to useIf the number of graph types you want to display is more than It s better not to mess up the information and make several graphs Other chartsThere are tons of different charts people have invented We list some of them without a detailed review Radar polar chart Scatter chart Bubble chart Geo chart Sankey diagram Timeline chartAnd that is not an exhaustive list of possible chart types Developers managers and analytics all over the world adjust graphs to their needs Charts become more tailored to the area where they are applied however almost all charts can be constructed out of charts listed above For example a stock chart that displays the exchange rates of currencies is a line chart with several series A Gantt chart that is used for project management is based on a horizontal bar chart If you want to get to know about most of the existing charts charts to be exact read this article Among specific features we would like to list some additional features that are common for all types of charts and may be necessary for some applications Animation smooth and seamless animation provides a more consistent and nice user experience and increases the chances that users would like to work with your app Additional events for interaction with a chart charts may provide an option to attach custom events to any rendered element When users trigger the event on click on touch for mobile for example some rendered elements can be modified altered or complimented Chart export an option to save the chart in a local file pdf jpeg png How to choose the right chart library When it comes to choosing the right chart library first of all you need to define the type of React chart your app needs We have mentioned some common pieces of advice when to use different chart types however we covered not a comprehensive list and maybe some tailored charts would cover your needs much better than classic pie bar charts The decision on which chart to work with must be based on the kind of analysis you are targeting to provide Another basis for making a decision is the way you want to represent the data to users We highly recommend to read about existing types of charts here and match your needs with the tasks every chart solves If you already know what kind of graph you need we gathered some factors you should pay attention to while choosing the chart library The list How many stars on Github a library has It is popular among developers Do they trust the chart and use it in their apps Is a Dev activity active or not Is a library well maintained with regular bug fixes new features deployment and issues solving What kind of support from developers is available Does the chart provide mobile support Is chart responsive out of the box Does it support touches and gestures Is the library well documented with examples and explanations of every feature it offers Does a chart offer additional features that you can use to make the user experience of working with charts much better Does the chart have some nice looking themes out of the box Does the library allow to customize the design of a chart What kind of customization does it offer Do you need SVG or Canvas output SVG is great for a small or medium amount of dataset while Canvas shows better performance when working with a large database Additionally it s worth mentioning two things that were not included in the criteria but which you need to know before you go looking for an ideal chart for you Most libraries are client side rendering while server side rendering charts are exceptions If it is not a problem and you are not looking for a server side rendering library we keep going Another thing you need to know most of the libraries depend on d js D is a popular JavaScript library with k stars on GitHub for visualizing data using Canvas SVG and Html It s a library with huge Dev activity plenty of videos tutorials books etc It stems from a low level approach and gives the developers freedom to create their own charts For what is this information If you are good at D or have an intention to level up in it you should consider an option to write your own charts library It may become a very good solution if you want to make a solution special for your use case Top React ChartsWe start from the most popular charts libraries for React You can find a lot of chart types in every library so you can look through them first The top itself is divided into several abstracts by the chart types Most popular charts
