Image-Charts
Image-Charts is the maintained successor to Google's retired Image Charts API, turning a single GET or POST URL into a rendered bar, line, pie, radar, GraphViz, or QR code image with no server-side rendering of your own. Chart parameters (type, data, size, colors, labels) are all encoded in the query string, and QR codes can additionally be requested as SVG via chof=.svg. The free tier stamps a small watermark on every image; removing it requires the paid Business plan.
