This area chart displays the USA population from 2010 to 2022, showing a smooth trend line over time. The visualization uses D3 v5 with SVG rendering, employing `d3.line` and `d3.area` generators with basis curves to create the line and filled area. Axes are constructed using `d3.axisBottom` and `d3.axisLeft`, with linear scales for both population and year values. Data is loaded from a CSV file hosted on GitHub Gist, with the population values formatted using `d3.format`.
