Summary

AI summary

Browser, static SVG, and MCP rendering paths are aligned on chart-mode defaults, styling, legend layout, histogram configuration, and specialized renderers.

Full changelog

Added

  • Narrative examples. Added Earthquakes and Europa Languages examples,
    including deterministic data fixtures and example-gallery previews.

Changed

  • Browser/server rendering alignment. Browser, static SVG, and MCP render
    paths now share chart-mode defaults, line and geo styling, legend layout,
    temporal histogram configuration, and specialized network, geo, gauge, and
    custom-chart rendering behavior.
  • SSR parity coverage. Replaced the redundant SSR/CSR screenshot matrix
    with semantic markup and targeted geometry assertions, while retaining the
    dedicated cross-browser visual suite.

Fixed

  • Docs example route smoke test. The route contract now targets the
    ExamplePageLayout title specifically, and the Earthquakes dashboard uses a
    nested heading level instead of duplicating the page's H1.
