A Chart.js chart needs a canvas element, the library from a CDN or npm, and a JavaScript config. Ours is a form: labels, numbers, download.
Chart.js documents PNG and JPEG output from its canvas; its docs don't cover SVG or PDF. Ours downloads both.
Download the chart once and insert it into a document, a slide or a post.
Chart.js draws interactive charts in your web page, with hover effects such as hoverOffset.
Offsets, spacing, rounded arcs and half circles are all options you can set.
Chart.js output is your own canvas. Our free downloads carry a small credit line until you buy Pro ($7.99 once).
Type or paste your numbers, then download PNG, JPEG, SVG or PDF.
