This area chart displays the population of the USA from 2010 to 2022, with a yellow line and a green filled area beneath it. The visualization uses D3 v5’s `scaleLinear`, `axisBottom`, `axisLeft`, and the `area()` generator with `curveBasis` to create the smooth filled region. Data is loaded from a CSV file via `d3.csv`, and the SVG output includes styled axes and labels. The code also draws the line using `line()` with the same curve, rendering the chart entirely as SVG elements.
