This visualization shows population growth over time for the first five countries in a CSV dataset, displaying semi-transparent overlapping area charts for each country. The code loads data via `d3.csv`, parses population values across nine census years, and uses `d3.scalePoint` for the x-axis and `d3.scaleLinear` for the y-axis. It generates areas with `d3.area()`, colors them via `d3.schemeCategory10`, and renders with SVG paths, axes, and text labels. The chart includes a title, axis labels, and country labels positioned near each area’s final value.
