This area chart visualizes US airline traffic data from the VizHub dataset, showing trends over time through a filled line graph. The D3.js v7 implementation renders a single steelblue line with white-stroked data points, set against a light gray background with subtle borders. Using the standard `d3.select` and `d3.axis` APIs, the chart generates crisp axis lines and labels within an SVG container. The visualization employs a simple linear path to connect data points, with CSS styling for the chart layout, providing a clean presentation of passenger volume patterns without interactive features.
