Description

Hi Eric, You saw this in person at the tutorial at SciPy, but here's a ticket for your reference. I get an error when trying to produce a Circos plot using the code in cell 3 from the notebook 4-cliques-triangles-structures-student.ipynb from the SciPy 2018 Network Analysis tutorial.

What I Did

# Make a Circos plot of the graph
from nxviz import CircosPlot

c = CircosPlot(G)
c.draw()

Yielded error:

---

AttributeError Traceback (most recent call last) in () 2 from nxviz import CircosPlot 3 ----> 4 c = CircosPlot(G) 5 c.draw()

This error could be because of a change in networkx version. In Networkx 2.1 for a graph G, G.nodes() is not a list hence "index doesn't" work.

Thanks for pinging in, @ChakreshIITGN! Can you tell me your version of nxviz? In master, this bug should be fixed; however, if you're using an earlier version of nxviz, the incompatibility bug might still be around.

Argh! I didn't read the ticket fully. My apologies!! Responding while in meetings is a very bad idea.
