It is possible to show the images of selected points by using two layered charts: ```py import altair as alt import pandas as pd source = pd.DataFrame.from_records( [{'a': 1, 'b':...

Great! Thanks for sharing your code! I will keep this open as a reminder to add something along these lines to the docs.

I didn't realize that `value` comes from vegalite, I thought it was a convenience function in altair. I will change this issue to add documentation on their differences as per...

Not sure if the doctest will also serve a live preview, but in case it doesn't, here is screenshot of what the section looks like now: 

Thanks @harabat , that's a good point you bring up. I was personally thinking about this section as tools that are more directly related to Altair rather than just compatible...
