A drop-in Google Image Charts alternative
Google Image Charts (the old chart.googleapis.com / Google Chart API) was deprecated and shut down. YakCharts is the modern, maintained way to get the same thing: a chart image from a single URL — still no JavaScript, still just an <img> tag.
Same idea, still maintained
If you built emails, PDFs or dashboards on Google Image Charts, you already know the model: encode the chart in a URL, drop it in an <img>. YakCharts keeps that model and adds 28 chart types, 9 themes, custom themes, HMAC-signed URLs, and quota you control.
Why not just Chart.js?
Client-side libraries need a browser and a build step — neither exists inside an email, a PDF, a README or a Slack message. A URL that returns a PNG works everywhere an image works.
Migrating is one host swap
Point your old URL at yakcharts.com/gchart — the legacy cht/chd/chs/chl/chco query string renders as-is. Example: /gchart?cht=p&chd=t:60,40&chl=A|B&chs=500x300. Or use the native API (type, data, title, options) — see the docs for the mapping and code in 5 languages.
Put this chart in your own emails, reports and dashboards
YakCharts turns data into a PNG from a single URL — no charting library, no JavaScript, no screenshots. Free tier included; every plan has all 28 chart types.
