{"version":"1.0","type":"rich","title":"Cheap Tricks for Interaction(Even cheaper with CSS)","description":"This example demonstrates a zoomable world map with interactive country selection, where clicking toggles a filled highlight state. It uses d3.geoNaturalEarth1 and d3.geoPath to render TopoJSON country boundaries from the world-atlas dataset, combined with d3.zoom for panning and scaling. The effect relies on CSS :hover and a .selected class triggered via d3’s event handler, supplemented by SVG <title> elements for tooltips. The render loop binds the country features and appends path elements to the SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/928506986bc14975bac4e96eba4cb488?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
