How to: Find common edges of a vertex.

Hello from Moldova. Here is a task i'm trying to solve in grasshopper, and looking for some advice. I have a mesh, and want to visulize how much edges are connected to each vertex.
I see it this way:

Any advices how to do it in grasshopper?

There is no component for directly getting mesh topology information in GH. In fact Rhino meshes don't intrinsically have edges at all. Edges are purely post-hoc data that can be reconstructed from the vertex-face relationships.

It is possible to generate this data using VB/C# scripting components though, though I'm the first to admit that our Mesh geometry class is not exactly a shining beacon of obviousness.

Here a way using native grasshopper components, but as you can see its very long winded but it does work for both Quads and Triangles (and probably a mixture of both but I haven't tested it)
