{"version":"1.0","type":"rich","title":"Cheap tricks for interaction","description":"This example shows a world map using the Hufnagel projection, where hovering over a country highlights it in yellow and displays its name via an SVG `<title>` tooltip. The visualization uses `d3.geoPath` with `geoHufnagel`, `topojson.feature` to parse country boundaries, and `d3.zoom` for pan-and-zoom interaction. Country names come from a TSV file matched to TopoJSON IDs using a reduce function. Styling relies on CSS for hover effects and sphere fill.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/74eeb2f7d56c4b9eb10199530cf842c0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
