{"version":"1.0","type":"rich","title":"D3 map","description":"This example displays a world map with color-coded countries and circular markers positioned at geographic coordinates, each filled with a photographic image. It uses D3.js (v5) with the `geoNaturalEarth1` projection and `geoPath` to render the map, loading TopoJSON country boundaries from the world-atlas package. Data is fetched from a SPARQL endpoint via a query that retrieves images, titles, and latitude/longitude for cultural heritage objects. The code creates SVG patterns containing images and applies them as fills to circles positioned using the projection function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/215783b382404d23bc2f859b628742c0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
