A GIF demoing interaction with an ipympl Matplotlib figure. In the demo, Clicking a cluster opens a pop-up window with a new figure.

The background Matplotlib figure shown is rendered as an interactive ipympl widget and wrapped in IPyOverlay’s OverlayContainer, and shows a UMAP of clustered embeddings. Clicking a cluster or right-clicking and selecting an exhibit creates a click-and-draggable pop-up window containing a new visualization that plots more details for the selected cluster. Optionally, each pop-up window can show a line connecting the window to the center of the cluster it is associated with in the underlying figure.

Custom actions can be added as A right-click menu to any widget. This menu is specific to this Matplotlib UMAP and allows users to choose whether to open a violin or distribution plot for the hovered cluster.

If multiple separate “background” widgets (Matplotlib UMAP on the left and Plotly map on the right) are wrapped in an OverlayContainer, overlay widgets can be displayed and dragged over all of them.
