This visualization displays a world map with images of photographs positioned over the countries where they were taken. The map uses D3.js and the topojson library to render geographic boundaries, while a SPARQL query retrieves data from the Netwerk Digitaal Erfgoed API. D3's `geoNaturalEarth1` projection and `geoPath` generate the map, and fetched image URLs are plotted as SVG images at coordinates derived from each photo's latitude and longitude.
