{"version":"1.0","type":"rich","title":"D3 map","description":"A D3 map visualization plots museum objects from the Netherlands Digital Heritage Network’s SPARQL endpoint onto a natural Earth projection. Animated circular images, each representing an artifact, appear at their geographic coordinates with a bouncing transition. The map uses `d3.geoNaturalEarth1`, `d3.geoPath`, and TopoJSON world-atlas data for country outlines. Data cleaning functions parse date formats and filter entries to four-digit years, while SVG transitions with `d3.easeBounce` animate the markers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9da0f74938a7430abe34ab0558e51cec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
