Want charts straight from your backend, without dragging a browser along?
Try charts-rs: 27 chart types, straight to SVG. Need an image instead? PNG, JPEG, WebP and AVIF all work.
A bar chart takes 41 µs as SVG and 1.7 ms as PNG.

Most charts you'd reach for are there, 27 in all:
bar, line, pie, scatter, radar, candlestick, heatmap, funnel, waterfall, gauge, treemap, box plot, sunburst, sankey, tree, graph, histogram, chord, gantt, map, calendar, table...
Several in one picture? That works too.
How fast? Fast enough to draw a fresh one for every request (M4 Pro, one thread, 600x400):
bar: SVG 41 µs, PNG 1.7 ms
pie: SVG 52 µs, PNG 1.4 ms
sankey: SVG 71 µs, PNG 1.2 ms
line, 2 x 100 points: SVG 158 µs, PNG 3.4 ms
No headless Chrome to spin up, no Node.js to babysit.
Where SVG can be shown, send SVG: sharp however far you zoom, small, and you can add hover tooltips.
Where it can't (e-mail, chat apps, PDFs), send an image: PNG, JPEG, WebP or AVIF, any size you like, 2x included. Bring your own fonts; CJK works fine.
Where it fits in:
- alerts and bot messages with a chart (Slack, Telegram, Discord)
- daily and weekly e-mail reports
- PDF and Word exports
- server-rendered dashboards
- CLI tools and cron jobs
Write Rust, or just hand it some JSON, handy when the config comes in a req
