RGraph is a JavaScript charts library based on
HTML5 SVG and canvas. RGraph is mature (over 18 years
old) and has a wealth of features making it an ideal
choice to use for showing charts on your website.
Version 7.10 (released in January 2026) is the
latest version of RGraph and contains various updates
to the code which you can see on
the changelog page. There's
also a big tidy up in terms of comments and a significant
change to the way that the internal code is referenced which
should lead to a performance improvement in effects and
animations.
In the April 2025 (v6.21) release a new datagrid object
was added.
This makes it easy to add static or dynamic data
tables to your pages. It can be used whether you use the
canvas or SVG libraries or entirely standalone.
Get the latest version of RGraph (version 7.10, 18th January 2026) from

minified files and links to cdnjs.com hosted libraries.

Margin sizing tool

A simple margin sizing tool that may help you with the size of your
