Add ChartMultiSelect widget for multi-region selections#144
Merged
Conversation
Adds a new widget for drawing multiple persistent box/lasso selections on matplotlib charts, each tagged with a class label (a, b, c, d). Users can highlight individual selections for editing, delete them, undo the last one, or clear all. Features include draggable repositioning, class-button switching, and Python helpers (get_labels, get_mask, get_indices) for classification workflows. Includes light/dark theme CSS, marimo demo with two-moons and three-blobs datasets, and integration into docs. Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
