Plotly Express

Plotly Express is a terse, consistent, high-level wrapper around plotly.graph_objects for rapid data exploration and figure generation.

Note: Plotly Express was previously its own separately-installed plotly_express package but is now part of plotly!

This notebook demonstrates various plotly.express features. Reference documentation is also available, as well as a tutorial on input argument types.

You can also read our original Medium announcement article for more information on this library.

A single import, with built-in datasets
