This example displays two geolocated markers on a map, each with a title and description of a building. It uses a `map.geojson` file as the data source, containing point features with custom properties for labels and colors. The visualization renders the map using D3’s `d3.geoPath` to draw the geographic features, while the markers are positioned based on their coordinates. The code relies on D3’s force simulation (`d3.forceSimulation`) to potentially handle marker placement or interaction, though the static view shows the two points plotted directly.
