This area chart visualizes Italy’s population over time, with year on the x-axis and population count on the y-axis. The data is loaded from a CSV file using `d3.csv`, and the chart is rendered as an SVG path via the `d3.area()` generator, with linear scales (`d3.scaleLinear`) mapping the values. Axes are created with `d3.axisBottom` and `d3.axisLeft`, and the chart includes labels for both axes. The visualization uses D3 v7 and a clean, minimal design.
