This area chart visualizes population trends over years for the World and its major areas, using distinct colors per country. Built with D3.js, it employs `scaleTime` and `scaleLinear` for axes, a `d3.area()` generator with a monotone curve, and `axisBottom`/`axisLeft` for ticks. Data is fetched from a CSV URL and processed via `timeParse`. The SVG output includes gridlines, a title, and a legend, rendered with a color scale from `schemeCategory10`.
