There are many visualisation libraries in python out there and altair offers some original features. It offers a wide variety of charts, a grammar-like api, loads of interactivity features and the option of exporting directly to the browser.
The bar chart at the end of this video is created via;
(alt.Chart(plot_df) .mark_bar(color='lightblue') .encode(x='date:T', y='births:Q', color='month:N', tooltip=['date', 'births']) .properties(height=200))
