This choropleth map shows global population by country in 2022, with darker blue shading indicating higher population counts. The visualization uses d3.geoNaturalEarth1 for the map projection and d3.geoPath to render country outlines from TopoJSON data loaded via the world-atlas package. Population values are joined to country geometries using CSV data from a GitHub repository, with missing countries shown in gray. A sequential square-root color scale (d3.scaleSequentialSqrt) maps population values to the interpolateBlues color scheme, and hovering reveals a tooltip with the exact population via appended `<title>` elements.
