Visualize heterogeneous graph

Hello all

I am learning heterogeneous graph via this example : Loading Graphs from CSV — pytorch_geometric 2.0.4 documentation
I would like to visualize the graph built.

I thought about using the function via to_networkx() to access to networkx library and see the graph.

My problem is : heteregenous class seems to not have this function. Only data class.

How can I transform heteregenous data to data and then use to_networkx() ?

Any code/advices/ressources will be appreciated.
