Running ForceAtlas2 from a set position.

[jamjar919]

I am trying to render a complex network using the React-Sigma wrapper. I know the base structure of this network to be many nodes of degree one and some of a very high degree. To this end, I have preformatted my graph data with x and y coordinates that represent an approximate layout, with degree one nodes clustered around the nodes they are connected to. I then want to run the ForceAtlas2 simulation from this point. However, when I try to do this, the simulation appears to just randomise and change the initial positions of the nodes to be in the centre.

A GIF and some code is available on my SO post (https://stackoverflow.com/questions/64874518/running-forceatlas2-from-a-set-position-in-sigma-js) but I was wondering if anyone had had a similar issue and if they managed to fix it?

@jamjar919 replied you in SO, but in short is ForceAtlas2 expects higher scale of positions and it changes them significantly during first iteration.

Ah thought that might have been you! Cheers, will close this <3
