{"version":"1.0","type":"rich","title":"Fork of D3 Starter","description":"This example visualizes world population data from a 2024 Kaggle dataset using a choropleth map. The map displays each country’s population with a blue color scale, from light (low) to dark (high), based on the `Population 2024` column, while countries without data appear gray.\n\nThe visualization is built with D3 v7 and TopoJSON, using `d3.geoNaturalEarth1` for the projection and `d3.geoPath` to render geographic features. It loads world map geometry from the world-atlas package and the CSV dataset, then employs `d3.scaleSequential` with `d3.interpolateBlues` to map population values to fill colors. Interactive tooltips display exact population figures on mouseover, and a graticule and legend provide spatial and color context.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e8688687482b425bb9a8b8c722e84ddf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
