{"version":"1.0","type":"rich","title":"Activity 8 Map","description":"This example displays an interactive world map using D3 v5 and TopoJSON. It loads country boundaries from the world-atlas dataset and renders them as SVG paths using `d3.geoPath` with a `d3.geoEquirectangular` projection. The map applies a blue sphere background and green country polygons with an indigo stroke, while a `d3.zoom` handler enables pan and zoom transformations. Hovering over a country changes its fill color to maroon via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/09869eec3dd24ca6b77de07da59a6375?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
