This example maps six geographic points across the UK using a GeoJSON FeatureCollection, each point colored according to its `type` (Building, Grass, or Water) and sized by its `cost` property. The visualization renders the points directly onto an SVG canvas using `d3.geoPath` to project the coordinates, with the data loaded from a gist. A D3 selection binds the feature properties to circles, positioning them via the projection and applying categorical colors and radius scales to encode the attributes. No interactive behavior or transitions are included beyond the static representation of the dataset.
