      labelFor?: (value: string, channel: LegendChannel) => string;
      onResetOverrides?: () => void;

  }

  • Optionalcollapsible?: boolean

    Forwarded to SpecLegend. Default true, which is what this component hard-coded before 2026-08-27.

  • Optionalcorner?: "top-left" | "top-right" | "bottom-left" | "bottom-right"

  • OptionaldefaultCollapsed?: boolean

    Forwarded to SpecLegend. A floating legend sits OVER the canvas at up to 240px wide, so a dense scene often wants it to arrive collapsed and open on demand. Previously unreachable: the prop was dropped here, and the only workaround was to abandon FloatingLegend and position a SpecLegend by hand.

  • Optionalelements?: readonly LegendElement[]

  • OptionallabelFor?: (value: string, channel: LegendChannel) => string

    Forwarded to SpecLegend (issue #38): the channel argument lets one function label node types and relation types differently.

  • OptionalonResetOverrides?: () => void

  • Optionaloverrides?: readonly { scope: { nodeId: string } | { type: string } }[]

    R-13: forwarded to the legend for override disclosure.

  • OptionalsectionTitle?: (channel: LegendChannel, driver: string) => string

    Forwarded to SpecLegend (issue #38): heading wording per section, for legends whose audience should read "Relation", not edge color: relation.

  • spec: EncodingSpec

  • OptionaltestId?: string

  • Optionaltitle?: string

  • Optionalugm?: UGM

    R-17 (register, 2026-08-06): optional, matching SpecLegend. A floating legend over a structural scene passes elements instead; the two components stay in step.
