{"version":"1.0","type":"rich","title":"functioneel programmeren (herkansing)","description":"A world map visualizes the geographic distribution of museum collection items, with each item represented as a small circle colored by its country of origin. The visualization uses a Werner or Gilbert projection via `d3-geo-projection`, and renders country boundaries using `d3.geoPath` with TopoJSON data from `world-atlas`. Circle positions are calculated by projecting latitude and longitude coordinates fetched from a SPARQL endpoint querying the Network of Digital Heritage (NMVW) dataset. Hovering over a circle shows a tooltip displaying the country name. The code relies on D3 v5, TopoJSON, and SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/10ad4e38a33a4a00ba3c9e610c0727be?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
