This area chart visualizes the annual profit of an Indian restaurant over time using an SVG rendered with D3 v5. The chart plots profit in millions against recorded year, with a smooth basis curve connecting data points and a filled area beneath the line. The visualization uses D3’s `scaleLinear`, `axisBottom`, `axisLeft`, `line`, and `area` functions to construct axes and paths, with profit data parsed from a CSV file loaded via `d3.csv`. Styling is applied through external CSS for axis labels and the chart’s fill color.
