Support other visualization librairies

[MarieS-WiMLDS]

Current state

Only Altair plots can be stored in Skore.

Improved state

Other (if not all if possible, according to technical design?) librairies are supported by Skore.

Blocker

• define what lib should be added. I suggest: plotly, matplotlib and seaborn.

Indeed, I am not familiar with Altair (like Marie, I am much more familiar with plotly, matplotlib, seaborn) and I got the following error when using Altair:

MaxRowsError: The number of rows in your dataset is greater than the maximum allowed (5000).

and I believe 5000 rows is not much?

However, I found this in the documentation Large Datasets - Altair that explains how to let Altair plot more than 5000 rows, they have the following claim about their intended restriction:

This is not because Altair cannot handle larger datasets, but it is because it is important for the user to think carefully about how large datasets are handled.

But I think a junior DS does not need to trouble himself with that.

As soon as #303 is merged you'll be able to store any kind of raster/vector in the report. Hence matplotlib will be supported.

Could you provide a list of which library should be supported and some snippets of how to use them ?

This is a valid point, but then it asks the question: what makes other libraries able to plot large number of rows?

I can identify reasons why someone/a library would like to limit the number of rows:

• raster render time (once when the image is generated)
• vector render time (every time the image is rendered in the browser)

How do other (vector plotting) libraries deal with this issue? @sylvaincom it would be very useful to research a bit on the solution others provide.

@thomass-dev do you think it would be easy to support plotly as well? It is very popular.
