A world map visualization plots up to 1,500 geographic locations as animated circles, using a natural Earth projection and SVG rendering. It loads country boundaries from the world-atlas TopoJSON dataset and fetches latitude/longitude coordinates from a SPARQL endpoint via the data.netwerkdigitaalerfgoed.nl API. The code employs d3.geoNaturalEarth1, d3.geoPath, and topojson.feature to draw the sphere and countries, then appends circle elements that transition their radius with d3.easeBounce and staggered delays, creating a popping effect on the map.
