{"version":"1.0","type":"rich","title":" ice 8_country","description":"This example shows a choropleth world map of population by country, with darker blue shades indicating higher values and a gradient legend on the right. It uses d3.geoNaturalEarth1 and d3.geoPath to project and render country boundaries from a TopoJSON world-atlas dataset. Population values are loaded via d3.csv from a GitHub gist and mapped to a d3.scaleSequential with the interpolateBlues interpolator. Labels display three-letter country abbreviations, while d3.axisRight and a linearGradient define the legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4a6e31d4d87b46b0946aa844128d5859?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
