{"version":"1.0","type":"rich","title":"D3 map","description":"This example displays a natural Earth projection world map populated with thumbnail images of photographs, each positioned by geographic coordinates derived from a SPARQL query against the Network Digital Heritage Netherlands API. The map is rendered as SVG using D3’s `geoPath` and `geoNaturalEarth1` projection, while country boundaries come from TopoJSON world-atlas data. Photographs are fetched, cleaned, and plotted as SVG `<image>` elements, with hover effects using CSS `mix-blend-mode`. The code leverages D3’s `json` loader and TopoJSON’s `feature` method.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f7ad9acce9eb458aa1d1b33a3a8e3133?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
