This example creates an interactive orthographic world map in D3 v5 where points from a SPARQL query are plotted as animated circles. The visualization shows a black sphere with goldenrod country outlines, while white circles representing museum locations fade and bounce into place based on their latitude and longitude. The map uses `d3.geoOrthographic` projections, `d3.geoPath` for country features, and `topojson.feature` to load world-atlas data. Users can drag and zoom the globe, with `d3.drag` and `d3.zoom` handlers re-rendering the projection as needed.
