{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"A choropleth map visualizes national happiness scores by coloring countries according to their economy classification from the World Happiness Report CSV. The map uses a natural Earth projection via `d3.geoPath` and `d3.geoNaturalEarth1`, with color mapping through `d3.scaleOrdinal` and the spectral scheme. A custom legend component shows color categories, while zoom functionality is implemented with `d3.zoom`. Countries display tooltips with their name and economy type, and hover states change fill color to red.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/252801c8cdba4276a6762cba91d815ed?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
