JSXGraph was part of the European Erasmus+ program ITEMS (https://itemspro.eu https://itemspro.eu). Aim of that project (and related projects where JSXGraph is / was included) is to research on "digital learning" in STEM subjects. The technical focus was on including JSXGraph in moodle courses with the question types STACK and formulas. For this and for certain mathematical topics, JSXGraph has been adapted through out the project. JSXGraph has been started as a seminar at the University of Bayreuth in 2007. The list of developers is given in the copyright section of the source code, e.g. https://github.com/jsxgraph/jsxgraph/blob/master/src/jxg.js https://github.com/jsxgraph/jsxgraph/blob/master/src/jxg.js. After the students have left the University, the core developer team is much smaller. Luckily, meanwhile the user community is increasingly providing improvements and bug fixes.
