{"version":"1.0","type":"rich","title":"ICE-8 NIHA","description":"Two map examples show how D3.js renders geographic data with TopoJSON and custom projections. The world map uses `d3.geoNaturalEarth1` and a sequential blue color scale to encode population values from a CSV, overlaid with a graticule. The US map uses `d3.geoAlbersUsa` with state boundaries from `us-atlas@3`. Both use SVG paths via `d3.geoPath` and a fixed tooltip on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/df85c7e16f96400d9e13c7ac255527e7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
