This example displays a GeoJSON map of Ugandan districts, loading the data from a gist URL and logging it to the console. The visualization renders an SVG container sized at 960 by 500 pixels, with the district boundaries drawn using D3 v5’s `json` method for asynchronous data fetching. The code sets up the SVG selection and dimensions, but does not yet compute paths or render the map geometry; it only logs the fetched GeoJSON data to the console for inspection.
