Tooltips and cross-filtering

Icon Map maps are interactive by default. Hovering, selecting, and filtering all work together so a viewer can explore the data behind the map.

Tooltips

Each layer can define tooltip fields — the columns shown when a viewer hovers over a feature. For richer hover content, use a Panel in Tooltip mode, which follows the cursor and can hold text, images, and data-bound values.

Detail on selection

A Panel in "On selection" mode shows detail about the currently selected feature — effectively a popup or detail card that updates as the selection changes.

Cross-filtering

Layers, charts, and slicers that share a data source are linked:

  • Select on the map → the charts filter to the selection.
  • Click a chart (bar, point, slice, row) → the map layers filter.
  • Use a slicer → everything bound to that data filters.

Field links (across sources)

When visuals draw on different data sources, connect them with field links. A field link maps a column in one source to a column in another (Source A / Column A ⇄ Source B / Column B), so a selection on one can filter a chart built from the other — for example, selecting a region on a boundary layer filtering a sales chart from a separate table.
