{"version":"1.0","type":"rich","title":"ICE8","description":"This interactive world map visualizes country populations with a sequential YlGnBu color scale. It loads TopoJSON world boundaries via `d3.json` and population data from a CSV, then joins them through ISO country codes. The SVG map uses `d3.geoNaturalEarth1` and `d3.geoPath` to render countries, with hover tooltips and an axis-labeled gradient legend built using `d3.scaleSequential` and `d3.axisBottom`. Missing values are shown in gray.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/abbf511c8c194cf6945471fab424e2e9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
