Re: [igraph] Trees generations?

You can conduct a breadth first search from the root node and color each
node according to the distance:

>>> colors = ["red", "green", "blue", "yellow", "white", "black"]
>>> tree = Graph.Tree(n, d)
>>> for vertex, distance, _ in tree.bfsiter(0, advanced=True):
...   vertex["color"] = colors[distance]

This should work for at most six levels -- add more colors to the
"colors" list if you need. Alternatively, you can use a palette (e.g.,
GradientPalette) and numeric color indices.
