We can create this graph as follows. # Create a directed graph g = Graph (directed=True) # Add 5 vertices g.add_vertices (5) The vertices will be … Websimplify () removes the loop and/or multiple edges from a graph. If both remove.loops and remove.multiple are TRUE the function returns a simple graph. simplify_and_colorize () constructs a new, simple graph from a graph and also sets a color attribute on both the vertices and the edges. The colors of the vertices represent the number of self ...
