Embedded nodes in draw_multilayer

[thomasrobiglio]

Adresses #436. I am still working on this to try to change as little as possible to behavior of the function.

Quoting @thomasrobiglio :

Yes I thought the same about the nodes' shape. What can be more relevant is the following:

I am struggling to have a node collection returned when calling the function (which then allows to have the colorbars and the cool stuff we have for the standard drawing function).

This is because I need to create a separate Circle patch that is transformed into a 3D patch for each node (in each level) separately, and I have not managed to group these objects in a collection so far. I will keep looking for a solution, if you have ideas they are most welcome, I am a bit stuck--I have opened a draft pr #612

Yes, I thought that might be a problem. Matplotlib has different types of collections, including a PatchCollection with an example here. Would this work with the 3D patches?

Thank you @maximelucas! this is more or less the documentation I was looking at when working on this... let's see if I can find something that works :).

This could be a way out... to have the circles for the nodes drawn as polygons with many sides. It's not the best thing to do, but I could not find a way to use a collection of circle objects in 3d.

With a couple of tweaks, I should be able to make it work from outside as the function we have in the stable version now.

Could you show us what the viz would look like? Is it like your example in the issue you opened?

[thomasrobiglio]

Something like this---if you have more >20 points to build the polygon you cannot see that it's not an actual circle:
