Strategies to reduce jitter / stutter

[benny-noumena]

Hey there!

I ran into the issue where with many nodes (~1k) the force layout (used in a worker) produces fatal jitter as the forces may drag the node towards the opposite directions. This can even lead to a severe effect on people with epileptic issues and I would like to avoid this somehow.

The node positions are calculated by graphology but it seems that there is no protection for this. I thought I can handle it by measure the delta-distance and delta-angle in the nodeReducer but unfortunately it looks like changing x and y attribute at this point does not have any effect.

What would be the best strategy to address this problem?

Many thanks!
Benny

The force layout works well form small graphs. But for bigger graphs, I recommend you to use force atlas

Sadly it is force-altas :(

This is a very difficult topic. The best I can tell you is to play with the FA2 settings, to find how to use them to reduce jitter for you specific graphs.

One tip though: You can try to use Gephi Lite to fine tune the FA2 settings with a UI. The good news is that it uses the same implementation, and the form matches the available function settings.
