0.3.1 (2026-03-16)

New Features

  • Lasso selection: New lasso mode for freehand point selection in the 3D canvas, with point-in-polygon hit testing
  • Selection highlighting: Selected points show wireframe highlight rings and non-selected points are dimmed to 15% brightness
  • Auto-sizing: Width defaults to 100% (fill container), height defaults to 1:1 aspect ratio. Both can still be set to fixed pixel values

Bug Fixes

  • Properties panel: Panel is now always created (previously skipped when show_properties=False), so the toolbar button always works. Starts closed unless show_properties=True
  • Distance metric feedback: Changing the metric now auto-enables k=5 connections when a point is selected, giving immediate visual feedback

Improvements

  • Reduced scroll zoom sensitivity (zoomSpeed halved to 0.5)
  • Search filter dimming increased from 12% to 6% opacity for clearer visual contrast
  • Camera no longer resets on every point update (only on initial load)
  • Cross-widget filtering: example updated so VectorSpace lasso selection feeds back into ParallelCoordinates dimming via marimo reactivity
