Correctly using NetworkModule visualisation to visualise a network

[MechaKaradi]

Hey! I am new to Mesa and ABM modelling in general and am attempting to implement a disaster response model that runs on a city's street network as a grid. I am struggling to get the visualization of the model to run in the inbuilt visualization server.

I have created the network graph using the nx library, and am able to view it correctly using the draw_networkx function. I have also defined a network_portrayal function under the server.py file modeled after the boltzmann_wealth_model_network visualization example in the examples repo. The python scripts don't give me any errors when run, however, the visualization server comes up blank and the javascript console shows: TypeError: t.app is undefined content_script_bundle.js:93:1027

The documentation isn't super clear about what could be wrong. Has anyone encountered this bug before?
What could be the cause?

I am attaching a link to my repository for this project in-case someone wants to take a look at my code.

Thanks!

The error message I got is Uncaught Error: node not found: 15012.
TypeError: t.app is undefined content_script_bundle.js:93:1027 this is probably one of your Chrome/Firefox extension's problem.

The error is due to street_network.data has the node indices starting from 1, 2, 3, ..., but D3.js assumes the nodes start from 0, 1, 2...
To fix the node not found error message, you rename node 15012 to node 0:

self.G = nx.relabel_nodes(self.G, {3999: 0})
