Is there other dataset where there's only one graph like MNIST?

Questions
#1

Hi,

I saw this example where all mnist images represented on the same graph. I wonder if there’s any other example/dataset in dgl that’s similar to this example, where there’s multiple signals but only one graph.

Thanks!

Skeleton-based action recognition and some brain graphs from MRI images are good examples, although for brain images I forgot what the specific paper is.

Thanks for the example!! I looked it up and both can be formulated into multiple signals but single graph problem.
