JSXGraph ========

JavaScript library for interactive math visualizations in the web browser.

About -----

JSXGraph is a cross-browser library for interactive geometry, function plotting, charting, and data visualization in a web browser. It is implemented completely in JavaScript, does not rely on any other library, and uses SVG, canvas, or even the venerable VML. JSXGraph is easy to embed and has a small footprint. No plug-ins are required! Special care has been taken to optimize the performance.

JSXGraph supports multi-touch events and runs on all major browsers.

JSXGraph is developed at the Lehrstuhl für Mathematik und ihre Didaktik and the Center of Mobile Learning with Digital Technology, University of Bayreuth, 95447 Bayreuth, Germany

  <div id="jxgbox" class="jxgbox" style="max-width:800px; aspect-ratio: 1/1;"></div>
  <script>
    var board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-8, 8, 8, -8]});

For developing content, it is recommended to include jsxgraphsrc.js (jsxgraphcore.js is the minified version of jsxgraphsrc.js). For further usage instructions please consult our wiki especially our tutorials or the API reference docs.

Build and develop JSXGraph --------------

1) Clone this repository or download the zip file. 2) To build and develop JSXGraph you need node.js v0.6+. First, install all dependencies required to build JSXGraph using npm in the JSXGraph root directory: $ npm install. This will create a new subdirectory ``node_modules` in the JSXGraph root directory which holds all tools and libraries required to build `jsxgraphcore.js`. 3) To build JSXGraph run $ npm run buildCore. This will output an non-minified version jsxgraphsrc.js and the minified version jsxgraphcore.js into the folder distrib. 4) Develop JSXGraph: - Edit the source files in the folder src - Write unit tests in folder test - Run $ npm run eslint and $ npm run test to check for errors - Run $ npm run check-format to check the formatting of the source code - Submit a pull request
