{"version":"1.0","type":"rich","title":"D3 map","description":"This example displays a natural Earth projection world map with photo thumbnails plotted at geographic coordinates. It queries the Network Digital Heritage SPARQL endpoint for image URLs and latitude/longitude pairs, then renders the images as SVG elements using d3.geoPath and d3.geoNaturalEarth1. The map itself loads TopoJSON world boundaries from the world-atlas package. Hovering over an image appends a text label via an event handler. The visualization uses d3.json for asynchronous data loading and d3-selection for DOM manipulation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f8f0698d812b4e4d8faaeadf76453833?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
