What it does
QuickChart turns a chart definition in the URL into a chart image, using Chart.js syntax: bar, line, pie, doughnut, radar and many more types, as PNG, SVG or PDF. That makes it easy to put charts in e-mails, Slack messages, PDFs and anywhere else where JavaScript does not run. It also creates QR codes, and can serve as a drop-in replacement for the retired Google Image Charts. Free plan with a monthly limit; paid plans for more charts. Open source, so you can also host it yourself.
