Abillity to Mutate Node Graph of simulation?

[codecnotsupported]

I was wondering if there was a reason why there isn't some functionality to add/remove nodes or link/unlink nodes of a existing Simulation.

Thank you for comment! The main reason for not having that functionality in the code yet, is because I couldn't come up with a good API yet—but it would be very nice to have something similar to d3.select (selection joins, with enter, exit, and update sets).

An option to emulate this behavior even now, is to rebuild the simulation (with the previous node positions as initial positions). We use that currently in Rerun and it seems sufficiently fast for our use cases, you can take a look here: https://github.com/rerun-io/rerun/blob/main/crates/viewer/re_view_graph/src/layout/provider.rs. Note that this requires keeping track of the nodes in your application code, though.
