layerchart@2.0.0-next.49

Minor Changes

• feat(Labels): Add smart placement option (#799)

  New placement="smart" mode that dynamically positions labels based on neighboring point values (peak, trough, rising, falling) to reduce overlapping.

• feat(Chart, BrushState): Add band scale (categorical) support for transform pan/zoom and brush selection. Uses range-rescaling pattern to smoothly zoom and pan categorical bar charts. Automatically constrains panning to data boundaries and prevents zooming out past initial view. (#449)

• feat(Chart): In projection mode, scaleExtent and translateExtent are now interpreted as relative values (like d3-zoom). scaleExtent: [0.5, 8] means 0.5x to 8x of the fitted projection scale. translateExtent is offset from the initial fitted position in pixels. (#449)

• feat(Spline): Support function-valued stroke, fill, and opacity for per-segment styling (#449)

• feat(Text): Add format prop and tween numeric value when motion is configured (#449)

Patch Changes

• Support tickSpacing for band scales on Axis, thinning tick labels when the domain is larger than the available space. Automatically shows more tick labels when zoomed in on band scale transforms. (#449)

• perf: Optimize primitive component instantiation (~3-5x faster for Rect, Circle, Ellipse, Line, Text, Path, Group) (#449)

  • createMotion: Fast-path passthrough when no motion prop is provided, avoiding $state/$effect overhead per axis
  • createDataMotionMap: Short-circuit when motion is undefined, skipping parseMotionProp overhead
  • createKey: Only create fill/stroke key trackers in canvas layer (skipped for SVG/HTML)
  • registerComponent: Skip registerMark for empty MarkInfo (pixel-mode marks)
  • All primitives: Skip $effect for data motion tracking when no motion is configured
  • Rect/Image: Avoid per-axis parseMotionProp calls when motion is undefined

• feat(Marker): Add square and square-stroke types (#805)

• fix(GeoPath): Fix canvas tooltip by conditionally passing onclick to Path, preventing non-interactive overlays from capturing hit canvas events (#449)

• fix(scaleBandInvert): Account for range offset in band scale inversion. Previously assumed range started at 0, causing incorrect pixel-to-category mapping when the scale range was transformed. (#449)

• fix(TransformContext): Reactively sync processTranslate and disablePointer to TransformState when props change. Fixes inverted globe dragging when dynamically switching between flat and globe projections. (#449)

• fix(Chart): Enable scroll zoom for globe projections by including scale: true in default transformApply for globes. (#449)

• feat(Raster, Contour): support bounded geo raster overlays with projected interpolation (#449)

• feat: Add Month component (#671)

• fix(LinearGradient, RadialGradient): Register as group instead of mark in canvas component tree so wrapped children (e.g. Arc, Path) are rendered (#449)
