This visualization combines bar charts and line charts to compare GDP and population across continents for 2024. The chart uses aggregated data from a CSV file, displaying GDP as blue bars and normalized population as a red line with points. Built with d3.csv, d3.rollups, and d3.scaleBand, the visualization maps population values to the GDP scale using d3.scaleLinear for comparison. The SVG rendering includes axes, legends, and tooltips, with d3.axisBottom and d3.axisLeft for the coordinate system.
