STACK and #MecLib
The MecLib library allows the creation of #Moodle #STACK #maths related questions with Graphics without having to write any #Javascript. It uses the JSXGraph library that comes bundled with #STACKmaths and the output can be customised purely within the casmaxima of the questionvariables field.
