possibility set some variable in url parameters

[jbar]

Hi,

First : Congratulation for this awesome project.

Second : Could be great to be able to surchage a know graph (json) with some data to be passed as url parameters.
Then we could define/redefine some value in url, instead of generating and share a complete new (graph) json.

Last : Being able to export/import a graph (json).
(Then we could start our own instance and stop using math3d.org's ressources).

++,
Jean-Jacques.
