This visualization plots bicycle shops in Glasgow using GeoJSON data from OpenStreetMap, with point and polygon features representing shop locations and building footprints. It shows the geographic distribution of bike retailers across the city, from central shops like Billy Bilsland to suburban outlets such as Clarkston Cycle Centre. The example uses D3.js with `d3.geoPath` to render the map shapes and likely employs a geographic projection to convert latitude-longitude coordinates into screen positions. The code processes the FeatureCollection to draw each shop as a distinct visual element, highlighting the spatial clustering of cycling-related businesses.
