As soon as I discovered Plotly I rushed to stick it into just about every project I had at hand, and was almost immediately...annoyed. My introduction to visualization in python came primarily from matplotlib and it's stylish counterpart seaborn; trying to work with Plotly to create charts of the same stylistic caliber ended up turning into a bit of a time sink. Enter Plotly Express - the far more intuitive, easily styled implementation of Plotly I wanted.
