Temporal arrangements of the nodes

[marcorobol]

Current arrangement of the graph in the 2d space is semantically meaningless, generated by pyhisical simulation just with the aim of improving graphical/spatial disposition of the nodes.

Solution

As a user I would like to see older nodes on the left and newer nodes on the right so to have quicker understanding of the process represented. Based on event/effect rule.

• Algorithm to order the nodes spatially, based on time or based on relationship they have one another
• Place the ordered nodes on a 2d space, maybe mixing up physics approach with event/effect constraints

Consider that some json have timestamps other does not. Here are some examples with timestamps:
