{"version":"1.0","type":"rich","title":"Cheap Tricks for Interaction","description":"This example shows a world map rendered with D3.js, using green countries that turn red on hover. The visualization demonstrates fundamental DOM manipulation and event handling through D3’s `select`, `data`, and `enter` methods, while `d3.geoPath` and `d3.geoNaturalEarth1` project the TopoJSON data from the world-atlas dataset. The SVG paths respond directly to CSS `:hover` styling, illustrating how inexpensive interactivity can be achieved with minimal JavaScript.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4a0c5e523b6a48fdb591585c6a8d0a2d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
