The route finding problem is the “traveling salesman problem”. And it shouldn’t be a tree. It finds the best path. A tree is rarely a path. But here’s a better...

Wikipedia gives some examples that might help. suppose you are laying down a new electric grid for a town. It is only feasible to build the route along existing roads,...

Yes, input 39 of the tutorial should indeed use ```(u, v, d)```. Thanks very much!

I think we envision your preferred set of notebooks -- 1-2 dozen notebooks each on a relevant Graph Theory application. Visualization and operations on text data (from literature? or journalism?...

The figures look good. It seems like plt.matshow could do much of this -- unless seaborn is using an algorithm to order the nodes. Does anyone know matshow well enough...

It look like they also cluster the nodes using scipy clustering algorithms, so its more than just showing the matrix. Very cool... :)

What do you mean by backfill? You can fill a node and you can set [textcolor and background color on text](https://matplotlib.org/api/text_api.html#matplotlib.text.Text)

You are correct -- while that property (and others) are available in matplotlib, the GraVE code doesn't pass through many text attributes to the label artists. Is there a reason...

Ahh -- in your example, the text is so large that it covers up the nodes. You have set the node_size to 20 but that doesn't seem to do anything....

I can verify that this is a bug! And your solution should work well. I suggest that we choose C to be the maximum weight plus 1, though there might...
