**Chart.js** is a free, [open-source](/source/Open-source) [JavaScript library](/source/JavaScript_library) for [data visualization](/source/Data_visualization), which supports eight [chart](/source/Chart) types: [bar](/source/Bar_chart), [line](/source/Line_chart), [area](/source/Area_chart), [pie](/source/Pie_chart) ([doughnut](/source/Doughnut_chart)), [bubble](/source/Bubble_chart), [radar](/source/Radar_chart), polar, and [scatter](/source/Scatter_chart). Created by [London](/source/London)-based [web developer](/source/Web_developer) Nick Downie in 2013, now it is maintained by the community and is the second most popular JavaScript charting library on [GitHub](/source/GitHub) by the number of stars after [D3.js](/source/D3.js), considered significantly easier to use though less [customizable](/source/Personalization) than the latter. Chart.js renders in [HTML5](/source/HTML5) [canvas](/source/Canvas_element) and is widely covered as one of the best data visualization libraries. It is available under the [MIT license](/source/MIT_license).[5][6][7][8]
