This area chart visualizes the relationship between age and diabetes outcome using the US Airline Traffic Dataset, with age on the x-axis and outcome on the y-axis. It uses D3 v7’s `d3.area()` to generate a filled path beneath the curve, applying a linear gradient for visual depth. The SVG rendering includes axis labels and scales via `d3.scaleLinear`, with data loaded asynchronously through `d3.csv`. The chart is styled with a light background and bordered container, providing a clear view of the data’s distribution and trend.
