Propose to add marsilea examples

[Mr-Milk]

Hi, thanks for developing such a fantastic website. It helped me a lot when I started with Python visualization years ago. Now I'm deep in the field, I have developed a new package called Marsilea for declarative creation of composable visualization in Python. Are you interested in checking it out and considering adding some examples with Marsilea? This project is still in a relatively early phase. Any feedback is welcomed!

I also developed a package called legendkit that helps customize legend styles and placement in matplotlib. It is used within Marsilea to create and layout multiple legends.

Some examples created with Marsilea, but you can do much more than what's shown below:
