{"version":"1.0","type":"rich","title":"Cheap Tricks for Interaction","description":"This example shows a zoomable world map rendered with D3 v5 and TopoJSON, where hovering over any country highlights it in red. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to draw country boundaries from the world-atlas 50m dataset, with country names added as tooltips using `<title>` elements. Interaction combines `d3.zoom` on the SVG for pan and zoom transformations, plus CSS `:hover` styling for the highlight effect. The base map and sphere are drawn as SVG paths, with data joined from TSV metadata and JSON topology.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d3c44789f8454c09ad16a09409e0bd70?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
