{"version":"1.0","type":"rich","title":"D3 map","description":"Semicircles animate onto a natural Earth projection, marking 1500 museum objects from a Dutch digital heritage SPARQL endpoint by their geographic coordinates. D3’s `geoPath` and `geoNaturalEarth1` render country boundaries from TopoJSON, while `fetch` retrieves and parses the query results. Circles use `transition().delay().ease(d3.easeBounce)` to pop in sequentially, overlaid on goldenrod countries and a black sphere.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7af7054277544049bca80095fb6cc03f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
