## What it is
GeoGebra is a suite of interactive mathematics applications including graphing calculators, geometry tools, a 3D calculator, a scientific calculator, and a notes app. This repository contains the Java source code of the GeoGebra apps, mirrored from the project's private GitLab instance.

## Use cases
- graph equations and functions interactively
- construct geometric shapes and explore geometry concepts
- plot functions in 3D
- solve equations and perform scientific calculations
- build interactive math lessons for students
- embed dynamic math tools in web pages

## When to choose
- you need an interactive graphing or geometry tool for teaching or learning math
- you want to build educational apps on top of GeoGebra's math engine
- you need a free calculator suite spanning algebra, geometry, and statistics

## When to avoid
- you need a lightweight command-line math library for scripting
- you require a permissively licensed codebase - GeoGebra has its own restrictive license
- you need a CAS-focused tool like SageMath or Mathematica for advanced symbolic computation

## Facets
- artifact type: application
- maturity: active
- function: gui, data-visualization, math
- domain: mathematics, education, cross-platform
- platform: cross-platform, jvm
- tags: graphing-calculator, geometry, cas, dynamic-mathematics, gwt, education-tools, web-server, desktop
