{"version":"1.0","type":"rich","title":"D3 map","description":"This example visualizes a world map with photographs plotted at their geographic coordinates. Built with D3.js and TopoJSON, it loads a Natural Earth map and renders it as SVG paths using `geoNaturalEarth1` and `geoPath`. It fetches sample photo data (with latitude, longitude, and image URLs) from a SPARQL endpoint, then places clickable thumbnail images on the map, projecting coordinates with the same projection. The map supports zooming and panning via `d3.behavior.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5bfbdcd9687248e19655bbae9540bda4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
