Software for drawing and analyzing a graph?

Question

I would like to know a good program for drawing graphs and analyzing them (finding Eulerian circuits, Hamilton cycles, etc.). I would also like to export the drawing to Word.

Answer 1

Why don't you try Sage -- it's free and should do as good a job anything else. You just type in

G = Graph (M)

for M an adjacency matrix to create your graph, then you can do

G.eulerian_circuit()
G.hamiltonian_cycle()

to find these things, and

plot(G)

draws your graph as a .png file which shouldn't be too hard to open in Word.
