How can I visualize a subgraph of my heterogenous graph?

[arymandeshwal]

So I created a link prediction model and explained it via CaptumExplainer and Explainer. After I get the subgraph from
explanation.get_complement_subgraph() I would like to visualize it, however for Heterogenous graphs, there's no method to visualize it yet.
And can anyone please explain some of my other doubts regarding Explainer, I am relatively new to it.

I am sorry for that. What you can try is to convert the HeteroExplanation object to an Explanation object by calling to_homogeneous, and visualize from there. This should hopefully work :)

I tried explanation.get_explanation_subgraph().to_homogeneous() however, I am unable to use visualize_graph()

[rusty1s]

How come? Because it is no longer a Explanation object? What happens if you create the Explanation object from these attributes?

data = Explanation.from_dict(explanation.to_homogeneous().to_dict())

[arymandeshwal]

is there any way to visualize it without converting it to homogenous as it loses information about node types.

Now it works, thanks a lot. However, is there any way to visualize it without converting it to homogenous as it loses information about node types.
