{"version":"1.0","type":"rich","title":"D3 map","description":"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.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c9ceebe10e6b4bb68e1975129833f4c2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
