This area chart visualizes India’s population over time, using a smooth curve to show the trend and an orange filled region beneath it. The chart includes labeled axes for year and sales, with grid lines and a bold title. Built with D3 v5, it uses `d3.line`, `d3.area`, and `curveBasis` to generate the path, with `scaleTime` and `scaleLinear` mapping data to SVG coordinates. Population data is loaded from a CSV file and parsed with `d3.csv` and `d3.timeParse`.
