This area chart displays the population trend from 2000 to 2013, using a smooth curve to show changes over time. The visualization loads CSV data, parses dates, and draws the line and area with D3 v5’s `scaleTime`, `scaleLinear`, `line`, `area`, and `curveBasis`. SVG rendering includes custom axes with tick formatting and colored labels. The chart emphasizes the area under the curve with a light green fill, while the line appears in black.
