Add visualizer

[Splines]

We want to visualize the Louvain algorithm. This could be done by instrumenting the code, e.g. write specific log statements, that can later be parsed by the visualizer to create the animation programatically, e.g. using Manim.

Important Requirement: We should be able to disable the instrumentation for release builds to not affect runtime.

What about big graphs? Animate camera as well?
