This example visualizes a world map with animated location markers derived from a SPARQL query against the Network Digital Heritage dataset. The map uses a natural Earth projection, with countries rendered as SVG paths via `d3.geoPath` and `topojson.feature`. Each data point is plotted as a circle whose radius transitions from 10px to 8px using a staggered delay and `d3.easeBounce`, creating a popping effect. The code loads world geometry from a TopoJSON file and fetches JSON results, converting latitude and longitude values before projecting them.
