{"version":"1.0","type":"rich","title":"Fork of Country Map","description":"This example displays a choropleth map of Italy, highlighting its regional borders and using a Mercator projection to shape the geographic outlines. The visualization is rendered as an SVG, with sky-blue fill for regions and black strokes for interior boundaries, while a hover effect changes the region color to PaleVioletRed. The code leverages D3 v5’s `geoMercator` and `geoPath` for map projection and path generation, TopoJSON’s `feature` and `mesh` functions to process geographical data from the italy.json file, and React with a custom `useData` hook to fetch and manage the data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/17b829809a1f4472ab2c8f6cdf06ba5d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
