What is QuickChart?
QuickChart is an HTTP service that renders charts and graphs as image files from query parameters.
It supports developers needing static visualizations for documentation, reports, emails, or server-side rendering.
What you can build with QuickChart
Embed charts in automated email reports
Developers generate chart images via URL and embed them directly in HTML emails or PDF reports without needing client-side JavaScript rendering.
Add dynamic visualizations to server-rendered pages
Teams use QuickChart to create on-the-fly chart images for dashboards and CMS content where browser-based charting libraries are not feasible.

Scripts call QuickChart endpoints to produce PNG or SVG chart images that are inserted into Word docs, slide decks, or internal wiki pages.
