Hey n0gare,
is the force-directed Graph visual in the Galary of Custom Visuals or is that visual Part of Microsoft?
First case try to download the pbiz file and open it with WinRar.
Second case try to download the zip of this repo: https://github.com/Microsoft/PowerBI-visuals-core
In the directory src/Clients/visuals you can find your visual maybe.
So i found the scatterplot visual.
Nice Regards
Mcburn
