Microsoft Automatic Graph Layout VS VL.Fuse

From my POV you don't need to try to find a special control for family tree but the idea is to use most common library like this. https://github.com/microsoft/automatic-graph-layout Then add you own logic to control the graph.

Check out Fuse[1/2]. It's an open source library for visually programming on the GPU. It is built for use in the visual programming environment vvvv[3].

VVVV itself is based on .Net and you can extend its functionality by either writing nodes in C# or import just about every existing .Net library just by referencing it or installing it as nuget. No need for wrappers[4]. For rendering vvvv uses the Stride [5] game engine which comes with a really neat shader system / language which is basically a superset of HLSL [6]. In vvvv those shaders are represented as nodes and you can open them in your favorite text editor directly from the vvvv evironment, edit the code, save and the changed result will instantly be loaded in vvvv[7].

We're using it as render engine for our visual live-programming environment vvvv: https://visualprogramming.net It allows you to play around with the engine fairly quickly. To get an impression, here is an intro tutorial that shows it in action: https://youtu.be/Cs60A_pSIy0 Also check out FUSE which builds on top of vvvv/stride: https://www.thefuselab.io/
