The same plot in 14 other libraries — Python: Altair, Bokeh, lets-plot, Matplotlib, Plotly, plotnine, Pygal, Seaborn; R: ggplot2; JavaScript: Chart.js, D3.js, Apache ECharts, Highcharts, MUI X Charts. Compare all 15 side by side: Activity Rings Progress Chart in Python, R, Julia and JavaScript.
An activity rings chart displays goal completion for several metrics at once using concentric radial progress arcs, in the style popularized by fitness trackers. Each ring is a partial arc with rounded end caps that starts at the top (12 o'clock) and sweeps clockwise in proportion to how close the metric is to its goal, with a distinct color per metric and a faint background track showing the full circle. It is instantly recognizable and ideal for at-a-glance comparison of progress across a small set of related goals, filling the general radial-progress gap that needle gauges (`gauge-basic`) and polar bars (`polar-bar`) do not cover.
