The following example shows how to save graphs of types
TNGraph, TUNGraph, and TNEANet for GraphViz:
import snap
Labels = { 0: "zero", 1: "one", 2: "two", 3: "three" }
Graph = snap.GenRndGnm(snap.TNGraph, 4, 6)
Graph.SaveGViz("graph1.dot", "Graph file", Labels)
UGraph = snap.GenRndGnm(snap.TUNGraph, 4, 6)
UGraph.SaveGViz("graph2.dot", "Graph file", Labels)
Network = snap.GenRndGnm(snap.TNEANet, 4, 6)
Network.SaveGViz("graph3.dot", "Graph file", Labels)
