{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes country-level scalar data using color-coding over a geographical projection. Built with D3.js, it renders SVG paths from TopoJSON world data, with the projection handled by `d3.geoPath` and `d3.geoNaturalEarth1`. The map assigns colors based on a `scalerank` attribute using a `d3.scaleOrdinal` color scale, while a supplementary color legend displays the mapping. Interactivity is included via a zoom feature, and hovering over a country highlights it and displays a tooltip with its name and value.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2e9216384fcc43579fe3335481895984?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
