## What it is
JSXGraph is a standalone JavaScript library for interactive geometry, function plotting, charting, and data visualization in the browser, rendering via SVG, canvas, or VML. It supports multi-touch, has a small footprint, and is developed at the University of Bayreuth for mathematics education.

## Use cases
- embed interactive geometry constructions in a web page
- plot mathematical functions in the browser
- build interactive math learning materials for students
- create charts and data visualizations with draggable elements
- add multi-touch geometry apps to e-learning platforms like Moodle
- visualize geometric constructions with points, lines, and circles

## When to choose
- you need interactive, draggable math visualizations in any modern browser
- you want a dependency-free, lightweight library embeddable via CDN
- you are building mathematics education content or e-learning tools
- you need multi-touch support for tablets and smartphones

## When to avoid
- you need server-side or non-browser rendering
- you need general-purpose scientific plotting with heavy datasets rather than interactive geometry
- you require a license more permissive than MIT/LGPL-3.0

## Facets
- artifact type: library
- maturity: stable
- function: data-visualization, charts, graphics
- domain: mathematics, education, data-visualization, web-development
- platform: browser, cross-platform
- tags: interactive-geometry, function-plotting, math-education, svg, canvas, dynamic-geometry, nodejs
