v1.31.0

1.31.0 (2026-10-07)

⚠ BREAKING CHANGES

• ChartModel.getData() now returns
  Partial<PlotData>[]
  using the PlotData type exported from @deephaven/chart instead of
  plotly's Partial<Data>[], and @deephaven/chart no longer depends on
  @types/plotly.js. These are just types breaking changes, there should
  be no
  runtime breaking changes with the @deephaven/js-plugin-plotly-express
  plugin.
