This area chart visualizes Cameroon’s population from 1960 to 2020, using a smooth curve to show growth over time. The SVG rendering relies on d3.area, d3.curveBasis, and d3.scaleTime for the x-axis, with d3.scaleLinear for the y-axis. Data is loaded via d3.csv from a GitHub Gist, and axes are drawn using d3.axisLeft and d3.axisBottom with gridlines.
