Summary

  • Add physical per-corner radii and semantic value-end radii for bar, rect, and cell marks across SVG, Canvas, and React Native.
  • Resolve rounded stack envelopes from final geometry, including negative, reversed, normalized mixed-sign, overlapping, and anchored stacks.
  • Relayout DOM charts when a CSS-owned container height changes while preserving explicit height and aspect-ratio precedence.
  • Support React 18 and React 19 peers, with strict React 18 packed-consumer type and warning-free SSR coverage for both React entry points.
  • Refresh the public docs, catalog previews, bundle baselines, and package-consumer checks.

Release impact

Changesets resolves this fixed package group to one 0.17.0 release:

  • @tanstack/charts
  • @tanstack/charts-scales
  • @tanstack/react-charts
  • @tanstack/react-native-charts
  • @tanstack/alpine-charts
  • @tanstack/angular-charts
  • @tanstack/lit-charts
  • @tanstack/octane-charts
  • @tanstack/preact-charts
  • @tanstack/solid-charts
  • @tanstack/svelte-charts
  • @tanstack/vue-charts

Validation

  • pnpm validate, all 19 CI tasks passed
  • 288 test files and 1,982 tests passed
  • 188 catalog previews and 102 documentation pages passed their contracts
  • Packed web, React 18, React Native, bare Metro, and Expo Metro consumers passed
  • Bundle policy and 60-case comparison checks passed
  • Standard browser conformance passed case 121 at 320, 640, and 960 pixels in both themes. Case 151 kept all 12 bars and paint parity across initial and updated scenes at every size and theme. Its existing shared label clipping remains at 640 and 960 pixels in both renderers.

Closes #28
Closes #130
Closes #133

Summary by CodeRabbit

  • New Features
    • Added selective corner rounding for bars, rectangles, cells, treemaps, and waffle charts, including per-corner and value-end options across SVG, Canvas, and React Native.
    • Added responsive height observation, including CSS-owned heights when width is fixed.
    • Added portable rectangle geometry helpers for custom renderers.
  • Bug Fixes
    • Improved animation settling, hit testing, and rounded-bar motion behavior.
    • Added React 18 support alongside React 19 and avoided server-rendering layout-effect warnings.
  • Documentation
    • Updated sizing, SSR, rendering, radius, and React compatibility guidance.

📝 Walkthrough

Walkthrough

This change adds selective corner radii for bars and rectangles, height-aware DOM sizing, React 18 peer support, server-safe effects, motion updates, interaction geometry, conformance coverage, documentation, and benchmark updates.

Changes

Chart behavior

Layer / File(s) Summary
Selective radius contracts and rendering
packages/charts-core/src/*, packages/react-native-charts/src/SvgScene.tsx
Bars and rectangles support uniform, physical per-corner, and semantic end radii. Renderers, hit testing, focus states, and motion use the resolved geometry.
Height-aware DOM sizing
packages/charts-core/src/renderer.ts, packages/charts-core/src/renderer.test.ts
The renderer observes container-owned content-box width and height. CSS-owned height changes update the scene when no explicit height or valid aspect ratio controls it.
Validation and conformance
packages/charts-core/src/*test.ts, benchmarks/conformance/*, scripts/*
Tests and tooling cover stack behavior, path output, animation, interaction geometry, responsive sizing, React 18 consumers, and path-based selectors.

React compatibility

Layer / File(s) Summary
React peer and SSR support
packages/charts-core/package.json, packages/react-charts/package.json, packages/react-charts/src/RendererChart.tsx, scripts/check-packed-consumers.mjs
React and React DOM peer ranges support versions 18 and 19. Browser rendering uses useLayoutEffect; server rendering uses useEffect. Packed React 18 consumers are checked through type and server-rendering validation.

Supporting updates

Layer / File(s) Summary
Documentation, release records, and benchmarks
.changeset/*, docs/*, packages/charts-core/docs/*, benchmarks/*, API-FRICTION.md, nx.json
Release notes, public documentation, bundle baselines, preview metadata, sizing guidance, and measurement budgets reflect the updated behavior.

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~120 minutes

Severity of issue fixed: Medium

Merge Risk: 🔵 Low · up to a42f3

This change adds selective bar and rectangle rounding, responsive height relayout, and React 18 support. One DOM-host documentation statement may overstate when rendering is skipped, creating limited guidance risk but no identified runtime failure.

Update the root wording and regenerate the package copy.

mountChartRenderer can render when dimensions are unchanged. Definition updates and forced renders bypass the dimension check. Change the root docs/reference/dom-host.md wording to “skips responsive relayouts”, then run pnpm docs:sync to update packages/charts-core/docs/reference/dom-host.md.

In `@docs/reference/dom-host.md`:
- Line 161: Update the height-observer statement in the host documentation to
clarify that height observation remains enabled only when CSS owns the height;
do not describe it as universally required when an explicit height or valid
aspectRatio is supplied.

In `@packages/charts-core/src/renderer.ts`:
- Around line 289-290: Update observesContainerHeight and the related
currentSize/responsiveSizeChanged sizing flow so height observation is enabled
only when CSS provides a non-auto container height, or otherwise measure the
content box instead of the border-box height. Preserve responsive sizing for
explicit height and aspect-ratio configurations while preventing repeated
scene-height growth in auto-height containers with padding or borders.

Align the validation count.

The F-296 entry reports 1,985 tests, while other validation records and the PR summary report 1,982. This mismatch can leave release material with a stale count. Update all records after the current pnpm validate result is available.
