{"version":"1.0","type":"rich","title":"asiign3-6(world-map)","description":"A choropleth world map colors countries according to population using a blue quantized scale. The visualization loads GeoJSON country boundaries from Natural Earth and joins them with population data from a CSV file via a country-name match. The code uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` to generate SVG paths, and `d3.scaleQuantize` with `d3.schemeBlues[5]` for color encoding. Countries lacking matching data are rendered in black.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c4200be96def431682f038b5830fd541?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
