v0.3.1

Fixes

• Prevent text selection on axis labels during interaction
• Distribute axes over a half-circle to avoid overlapping pairs with even axis counts
• Replace Gram-Schmidt basis completion with odd DFT harmonics for better rotational stability

Full Changelog: v0.3.0...v0.3.1

v0.3.0

Features

• Trackball rotation: Right-click drag on the canvas to smoothly rotate the 3D projection subspace, like spinning a globe. Applies an orthogonal rotation to columns 0–2 of the projection matrix.
• Mousewheel zoom: Scroll to zoom — adjusts FOV in perspective mode, scales the view in orthographic mode. Emits a new zoom event ({ viewAngle, zoomLevel })
• Normalized axis drag sensitivity: Axis handle drag now divides by the scale's half-domain, making sensitivity consistent regardless of data scale.

Examples

• Added MNIST PCA example (9 principal components, 10 digit classes)
• Added marimo notebook examples

Full Changelog: v0.2.1...v0.3.0

v0.2.1

• Fix infinite recursion in widget lasso event sync
• Add marimo notebook example

v0.2.0

What's new

• Lasso selection: Shift+drag on the canvas to draw a freeform polygon and select enclosed points. Unselected points are dimmed. Double-click or Escape to clear.
• Selection API: selectedPoints, setSelectedPoints(), clearLasso(), and "lasso" event with original data indices.
• Widget traitlet: selected_points syncs lasso selection bidirectionally between JS and Python.
• Python package metadata: Added license, authors, classifiers, keywords, URLs, and fleshed out README for PyPI.

Breaking changes

• Axis flip modifier changed from Shift+click to Alt+click on axis handles.
