Matchstick Graph Editor

Recently I created a specialized graph editor for matchstick graphs like the Harboth graph. It is not a fancy application but it works:

Try it out and load the data of the harboth graph into your editor!

Question: What is the minimal 1, 2 and 3-degree-matchstick graph in 2D?

Requirements:

In a 3 degree graph every node has exactly 3 edges
It must be a planar graph (edges can only intersect at the nodes)
Length of each edge is the same
Be the first and link to your matchstick.dat file(s)
Think about solutions for 1, 2, 3 and 4 degree matchstick graphs in 3D (easier than 2D)

Prizes: Win Experience and be listed here as a winner 😉 !

Conclusion

Getting starting and done was easy and fast within some hours. But debugging and writing tests in JavaFX (1.2 or 1.3) with NetBeans is not that good as described earlier
