Chart.xkcd
chart.xkcd is a client-side JavaScript library used to generate data visualizations as scalable vector graphics directly in the browser. It functions as a graphing utility that manipulates DOM elements to produce various chart types without requiring server-side dependencies.
The library is distinguished by a rendering engine that applies randomized stroke offsets and variable line weights to SVG paths. This process simulates a sketchy, hand-drawn aesthetic for data charts, creating a comic-like visual style.
The project supports a variety of visualization formats, including bar, line, circular, radar, and XY coordinate charts. It also provides capabilities for stacked bar charts to show part-to-whole relationships and combined charts that overlay different dataset types on shared axes.
The library is distributed as a single-file bundle for integration via a script tag and uses a JavaScript configuration API to initialize charts through plain objects.
