Looks pretty neat @AlejandroFernandezLuces -- I'd love to see more functionalities get added to it but as a starting point it's really good
Have we tried it with a library directly and see how it plays?

Overview
Add Plotly as backend. I added a simple example to show how to use Plotly as a backend with the plotter. Minor changes to the BaseBackend class were needed, since I didn't realize some issues until the new backend was added.
Endless features can be added to this backend, so for the moment let's add the basics and we can check what we need to add in further iterations. For the moment, it allows to plot PyVista meshes, MeshObjectPlot objects and Plotly objects. Later we can add the button/picking features from the PyVista backend or even other features that plotly allows.
Layout object from Plotly is exposed through a property to allow uses to customize it as they want. As you can see in their docs, customization is pretty extensive: https://plotly.com/python-api-reference/generated/plotly.graph_objects.Layout.html
Also, I had to implement a simple image comparison for testing Plotly plot outputs, which seems to be working fine from what I see in the image cache.
pytest-pyvistais not compatible with Plotly.Example
This is what the included example looks like:
