This area chart visualizes the profit in millions of an Indian restaurant over recorded years, with the data loaded from a CSV file. The chart displays a smooth, curved area and line path using D3’s `area` and `line` generators with the `curveBasis` interpolation, rendered as SVG. The axes use `scaleLinear` for both time and profit values, with gridlines and labels styled via CSS. The visualization is built with D3 v5, imported through ES modules, and styled with the Poppins font on a purple background.
