Gallery Examples Using Movies Data Don't Display

[Robbie-Palmer]

In the example gallery, under area charts, the Cumulative Count Chart isn't displaying

The field name needs updated from "IMDB_Rating" to "IMDB Rating"

The Binned Heatmap is another example that uses this dataset and needs underscores replaced with spaces to work

Sorry about that – the vega-datasets library deleted & moved a bunch of the datasets in a recent release, and Altair's docs have not yet been updated to reflect this.

No problem! Was easy enough to discover the reason and fix it to view the plots locally
But would be nice for Altair's gallery to be fully showing off what it can do 😊
