NetworkX coloring a node at runtime

I have as an assigment to implement bfs and dfs graph traversal with visualization. To do that, I'm using NetworkX in Python. What I want to know is how to color a node at runtime? For example, when I am at a specific node in bfs/dfs, to set it's color to red or something. I know how to color different nodes of a graph, but not at runtime. I thinked that a possibility is to draw again and again the graph, but I'm sure that this is time consuming. Any sugestions?

Thanks in advance!

NetworkX draws static graphs but you can mark visited and unvisited edges with different colour and thickness to see the walk process.

edgeSeq = [list of visited nodes]
nx.draw(G, pos, edge_color='gray',width=.2)
nx.draw(G, pos, edgelist = edgeSeq, edge_color='blue', width=2)

You may try Cambridge Intelligence trial to work with the time bar features.
