Interface: VisualizationLayer

Properties

activeLegendId?

optional activeLegendId?: string

Defined in: spec/types.ts:274

Id of the currently active legend from legends[].

---

clickAnchor?

optional clickAnchor?: object

Defined in: spec/types.ts:298

Spec-driven click marker. When present, geovis automatically places a visual indicator on the clicked feature without requiring a <GeoVisMarker> component. Three rendering modes — see field descriptions.

color?

optional color?: string

Accent colour for the built-in SVG pin. Applied when iconImage is not set. Default: '#3FB1CE'. For a custom HTML/React element, use <GeoVisMarker> instead.

iconImage?

optional iconImage?: string

MapLibre sprite icon name. Renders a feature-state-driven companion symbol layer at the polygon label point.

iconSize?

optional iconSize?: number

Scale factor for the sprite icon. Default: 1.

offset?

optional offset?: [number, number]

Pixel offset [x, y] applied to the DOM marker.

---

geometry

geometry: GeoVisGeometryType

Defined in: spec/types.ts:264

---

hoverPaint?

optional hoverPaint?: object

Defined in: spec/types.ts:286

Paint applied via MapLibre setFeatureState({ hover: true }) when the pointer enters a feature. When present, the adapter adds a companion line layer (<id>-hover-outline) driven by feature-state expressions.

lineColor?

optional lineColor?: string

lineWidth?

optional lineWidth?: number

---

hoverTooltip?

optional hoverTooltip?: HoverTooltipConfig

Defined in: spec/types.ts:324

Spec-driven hover tooltip. When present, <GeoVisProvider> automatically renders a <GeoVisHoverTooltip> for features hovered on this layer — without requiring the component to be placed in the tree. Mirrors GeoVisHoverTooltipProps (render, formatValue, style, offset, emptyValueLabel, className). An empty object ({}) opts in to the default tooltip layout. Typed via a type-only import so the data-only spec layer keeps no runtime dependency on React.

---

id

id: string

Defined in: spec/types.ts:262

---

legends?

optional legends?: LegendSpec[]

Defined in: spec/types.ts:272

Optional alternative legend definitions presented as runtime toggles.

---

mapDataId?

optional mapDataId?: string

Defined in: spec/types.ts:280

Optional reference to an entry in spec.mapData. When present, the layer can be styled/queried by per-feature values coming from the dataset (joined via feature.id or mapData.joinKey).

---

maxzoom?

optional maxzoom?: number

Defined in: spec/types.ts:269

---

minzoom?

optional minzoom?: number

Defined in: spec/types.ts:268

---

paint?

optional paint?: LayerPaint

Defined in: spec/types.ts:270

---

selectedPaint?

optional selectedPaint?: object

Defined in: spec/types.ts:292

Paint applied via MapLibre setFeatureState({ selected: true }) when a feature is clicked. When present, the adapter adds a companion line layer (<id>-selected-outline) driven by feature-state expressions.

lineColor?

optional lineColor?: string

lineWidth?

optional lineWidth?: number

---

sizeBy?

optional sizeBy?: SizeBy

Defined in: spec/types.ts:330

Proportional symbol configuration. When present on a point layer, circle-radius is driven by a data expression instead of a static value. Ignored on non-point geometries.

---

sourceId

sourceId: string

Defined in: spec/types.ts:263

---

sourceLayer?

optional sourceLayer?: string

Defined in: spec/types.ts:265

title?

optional title?: string

Defined in: spec/types.ts:266

visible?

optional visible?: boolean
