Consider putting up an example, in the example folder, on using Argoverse map and traffic. Add the Argoverse example to the CI tests. Update how to use SMARTS for Argoverse under Ecosystem section in ReadTheDocs.

When we finish adding color configuration for those actors, maybe we could consider giving the is_ego_vehicle a different color?

There is an example scenario in this PR that uses an Argoverse map and traffic histories that should work with any example. Is there something you had in mind that is not covered by that?

It would be good to have some tests, but I was unsure if the license allowed us to host the dataset files.

I will update ReadTheDocs -- thanks for the reminder.

With regards to the Argoverse example, we could do something similar to the suggestion for Waymo example at #1905 (comment) .

I have added an Argoverse section to ReadTheDocs, with instructions for running an example scenario and a gif of the expected visualization. I opted not to create a new example script as this didn't seem necessary.
