{"version":"1.0","type":"rich","title":"Cheap Tricks for Interaction On a D3.js World Map!","description":"This example shows a zoomable world map built with React and D3 v5, where hovering over a country highlights it in red and displays its name as a tooltip. The map renders SVG paths using `d3.geoPath` and a Mercator projection, with geographic data loaded from the world-atlas TopoJSON and country names matched via TSV. Interaction includes a `d3.zoom` handler that transforms a group element containing all country paths, and CSS `:hover` rules change fill color. The code demonstrates combining TopoJSON feature extraction, data joins, and simple event-driven styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
