{"version":"1.0","type":"rich","title":"D3 map","description":"This example visualizes a world map with data-driven location points, plotting over a thousand geographic coordinates as animated circles on a natural Earth projection. It uses D3 v5 with `d3.geoNaturalEarth1`, `d3.geoPath`, and TopoJSON’s `feature` to render country boundaries from the World Atlas dataset, while querying a SPARQL endpoint from the Dutch Digital Heritage Network for latitude and longitude data. Each circle appears sequentially with a bounce ease transition, growing from zero to a fixed radius to show the distribution of the dataset across continents.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8551a882ac9047b198be030f9502ae87?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
