This area chart displays population changes over time for a single country, using data loaded from a GitHub-hosted CSV file. The visualization leverages D3 v7 to parse the CSV, transform it into year-population pairs, and render a scalable SVG area path. It includes labeled axes, a chart title, and uses `d3.area()`, `d3.scaleLinear()`, and `d3.axisBottom()`/`d3.axisLeft()` for the graphic layout. The chart fills the area beneath the line with a green tone, and the code also demonstrates ES6 module imports via a local helper file.
