Graph Neural Networks possible?

[Billaferd]

I am trying to learn about Graph Neural Networks and wanted to know if they are possible to build using this library.

I see all of the basic building blocks, but I couldn't find how to create a layer that is connected in the same way as a graph, I was looking for someway to provide an adjacency list but was unsuccessful.

Is there an example to show how, or clarity on if it is possible with this library?

Thanks!
