{"version":"1.0","type":"rich","title":"Cheap Tricks for Interaction","description":"This interactive map uses a natural Earth projection with D3’s `geoPath` and `geoNaturalEarth1` to color countries by economic classification, employing a spectral `scaleOrdinal` and a custom color legend with circles and text. Zooming is enabled via `d3.zoom`, while hovering highlights countries in red through CSS. World map geometry comes from TopoJSON’s `world-atlas`, enriched with metadata from a TSV file. The example demonstrates simple, reusable interaction patterns—tooltips via SVG `<title>` elements and a hover effect—without complex brushing or transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e5c5f6f932c14afeae8160bd9bf4d8e6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
