The seaborn.objects namespace was introduced in version 0.12 as a completely new interface for making seaborn plots. It offers a more consistent and flexible API, comprising a collection of composable classes for transforming and plotting data. In contrast to the existing seaborn functions, the new interface aims to support end-to-end plot specification and customization without dropping down to matplotlib (although it will remain possible to do so if necessary).

The objects interface is currently experimental and incomplete. It is stable enough for serious use, but there certainly are some rough edges and missing features.

The seaborn.objects namespace will provide access to all of the relevant classes. The most important is Plot. You specify plots by instantiating a Plot object and calling its methods. Let’s see a simple example:

This code, which produces a scatter plot, should look reasonably familiar. Just as when using seaborn.scatterplot(), we passed a tidy dataframe (penguins) and assigned two of its columns to the x and y coordinates of the plot. But instead of starting with the type of chart and then adding some data assignments, here we started with the data assignments and then added a graphical element.
