This scatter plot visualizes projected 2025 world population data, showing each country’s total population against its urban population percentage, with circle size encoding each nation’s share of the global population. Built with D3 v7, it renders as an SVG with linear scales for both axes and a square-root scale for radius. Interactive tooltips appear on mouseover, displaying the country name, population, urban percentage, and world share. The chart loads data from a CSV file and uses D3’s `d3.csv`, `d3.scaleLinear`, and `d3.scaleSqrt` APIs.
