It would be cool if this package's functionality could be made available via a submodule in altair:

from altair import aly

aly.nan()

or maybe:

import altair as alt

alt.aly.nan()

It would put much higher demands on the code quality and stability so less rapid development, but could still be labeled as a more experimental part of the altair package if everything was contained in a submodule/folder. It would increase the visibility of these functions a lot which I think would be useful for many people

Currently sorted by index but could be by any variable, especially catecoricals would be interesting, This would be similar to the current heatmap sorting. Some more ideas here https://statistikat.github.io/VIM/articles/VisualImp.html not sure if scatters etc are valuable

So that it is easy to set the width/height and title of each chart

To allow for a minimum level of customization. This largely works already, but need to double check that there are no edge cases or charts constructed a different way that does not allow for it (e.g. the looping). Also add to docs

Bottom of the page https://hvplot.holoviz.org/. Might have more perceived utility than actual utility so maybe not worthwhile. Nice as a demo tool though.

I'm not sure if this would be convenient or if it is enough to use the sort parameter in the api. I don't want to make things too dependent on interactions in the GUI. Could use something similar to this from Dylan Open the Chart in the Vega Editor

Thinking about this again: I think it could be great to create a heatmap that is sortable like this.

As in this example with ID and default...
