The visualization shows all cafés located within the administrative area of Groningen, using OpenStreetMap data to map their positions as clickable markers with pop-up name labels. It begins by displaying the geographic context of the city before highlighting the distribution of café locations. The code constructs a Leaflet map and queries the Overpass API for nodes tagged with `amenity=cafe` inside the Groningen boundary. The response is converted from OSM XML to GeoJSON using the `osmtogeojson` library, then rendered as a vector layer via `L.geoJson`, with the map view automatically fitting to the café bounds.
