Change Node Display Size in Networkx

I am not using GraphViz because I am having problems with making it play nice with Networkx. I know this is weird, but I've tried many suggestions to fix this problem, but I just seem to have some of the worst luck in the world. Therefore the problem that I have must be solved withing Networkx without using GraphViz.

My program reads a document and and tries to draw something of a MindMap based on the contents of the document. However, Networkx seems to have a default size when it comes to actually drawing the node. This is bad for me because a lot of text goes into each of my nodes. I need a way to increase the display-size of my nodes (arbitrarily, based on the size of the text that belongs in that node).

I have tried looking at the Networkx site, othe开发者_C百科r questions on SO and about 200 search results from Google, with no luck.

Try nx.draw(G, node_size=size), where size can be a scalar or an array of length equal to the number of nodes.
