This choropleth map shows global population by country, with each nation colored on a blue sequential scale based on its total population. The visualization joins World Geojson map features with population data from a CSV file using their shared ISO-3 country codes, rendering countries with missing data in gray. Built with D3 v7, it uses d3.geoPath with an equirectangular projection and d3.scaleSequential for color encoding, while interactive tooltips reveal country names and formatted population values on hover.
