Hi, I work on the same project.
This tutorial is only for animating through the UI, but we want to generate the animation from a CSV file (i.e. with a script), hence the JSFiddle. It would be completely unpractical to create the key frames manually, copying the values from the CSV.
Do you have any doc to do this ? I believe v1 is only from scripting inside the modeler, not for the embedded viewer, and the v2 doc is non-existent (for animation creation/editing).
