{"version":"1.0","type":"rich","title":"D3 Course Code Along - Create Map","description":"This example visualizes world population growth from 1000 to 2020, mapping countries on a natural Earth projection using D3 v5. It loads TopoJSON world atlas data, converts it to GeoJSON with the `feature` method, and renders each country as an SVG path via `d3.geoPath`. The code also draws a sphere outline and alternates between `geoMercator`, `geoOrthographic`, `geoStereographic`, and `geoNaturalEarth1` projections, with data from a CSV file displayed alongside the map.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/615137ecd8854c1f83093695086adc0e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
