    React Chart.js

    React Chart.js

    React components for Chart.js, the most popular charting library

    React components for Chart.js, the most popular charting library. With v4, this library introduces a number of breaking changes. In order to improve performance, offer new features, and improve maintainability, it was necessary to break backwards compatibility, but we aimed to do so only when worth the benefit. You will find that any event which causes the chart to re-render, such as hover tooltips, etc., will cause the first dataset to be copied over to other datasets, causing your lines and bars to merge together. This is because to track changes in the dataset series, the library needs a key to be specified. If none is found, it can't tell the difference between the datasets while updating. Specify a different property to be used as a key by passing a datasetIdKey prop to your chart component.

    go-chart

    go-chart

    go chart is a basic charting library in go

    Package chart is a very simple golang native charting library that supports time-series and continuous line charts. Master should now be on the v3.x codebase, which overhauls the api significantly. Per usual, see examples for more information. Actual chart configurations and examples can be found in the ./examples/ directory. They are simple CLI programs that write to output.png (they are also updated with go generate. Everything on the chart.Chart object has defaults that can be overridden. Whenever a developer sets a property on the chart object, it is to be assumed that value will be used instead of the default. The best way to see the api in action is to look at the examples in the ./_examples/ directory. I wanted to make a charting library that used only native golang, that could be stood up on a server (i.e. it had built-in fonts). The goal with the API itself is to have the "zero value be useful", and to require the user to not code more than they absolutely needed.

    C3.js

    C3.js

    A D3-based reusable chart library

    C3 makes it easy to generate D3-based charts by wrapping the code required to construct the entire chart. We don't need to write D3 code any more. C3 gives some classes to each element when generating, so you can define a custom style by the class and it's possible to extend the structure directly by D3. C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even after it's rendered. C3 enables deeper integration of charts into your application. Because of the dependence on D3, C3 supports only modern browsers D3 supports. For IE9 and IE10, polyfill is required because c3 uses MutationObserver, which is not supported in those versions. However, it's not required if charts always will be binded to the DOM specified by bindto because MutationObserver is not called in that case.

    visx

    visx

    Visualization components

    visx a collection of expressive, low-level visualization primitives for React. At Airbnb, we made it a goal to unify our visualization stack across the company and in the process, we created a new project that brings together the power of D3 with the joy of React. visx is split into multiple packages. Start small and use only what you need. Bring your own state management, animation library, or CSS-in-JS solution. Odds are good your React app already has an opinion on how animation, theming, or styling is done. visx is careful not to add another one and integrates with all of them. As you start using visualization primitives, you’ll end up building your own charting library that’s optimized for your use case. You’re in control. And most importantly, it’s just React. If you know React, you can make visualizations. It’s all the same standard APIs and familiar patterns. visx should feel at home in any React codebase.

All the components expose some common API methods like width, height, and margin. Additionally, each chart or component can expose specific methods you can find in the documentation. Britecharts components are distributed in UMD modules, each one exposing a D3.js component written with the Reusable API pattern. To use any of the Britecharts modules, you will need to require the chart in your JS file using AMD/CommonJS modules or adding a script tag with the src pointing to the file.

Guide to Open Source Charting Libraries

Open source charting libraries are software tools that allow users to create, customize and share professional-grade interactive graphs and charts. These libraries typically have a wide variety of chart types available, including bar, column, line and pie graphs. They also provide functions for data manipulation so that the user can easily modify their data before creating a visualization. Charting libraries built on open source technologies also allow developers to extend the library’s capabilities by adding custom code or modules.

The most popular open source charting library is D3 (Data Directed Documents), which is an JavaScript library used in web development. It provides powerful yet flexible data visualization capabilities without needing extensive coding knowledge. Built on SVG technology, it allows users to create interactive graphics with features such as panning and zooming as well as animation effects like loading indicators or smooth transitions between different datasets. With its wide array of graphing options and ease of use, D3 has become one of the go-to tools for creating modern visuals for business intelligence applications or dynamic webpages.

Other popular open source charting solutions include Highcharts JS and ChartJs—both of which use HTML5 Canvas technology to generate images from numerical data sets at high speed and with minimal effort from the user. Additionally, both languages boast comprehensive documentation making them easy to learn even for beginners who don’t have prior experience with coding or visualizing data sets into charts. One key difference between these two solutions is that while ChartJs uses vanilla JavaScript syntax—making it lightweight compared to options like D3—HighCharts comes with included functionality such as technical indicators and annotations making it ideal for complicated financial analysis scenarios but also bulkier than other alternatives in terms of file size due to its greater level of detail returned upon every render request..

Overall there are plenty of great open source charting libraries available today that make it easy for anyone to get started quickly when it comes time to produce effective visuals from their datasets without needing extensive coding experience beforehand.
