altair: Turn off MaxRowsError
There are many things to like about Altair but you should be aware that it also has limits. The main downside is that it usually has a lot of trouble with drawing lots of datapoints. That's why it usually has a max-row warning turned on.
You could turn it off, but please be careful. Not every browser will be able to handle it.
import altair as alt
alt.data_transformers.disable_max_rows()
