This example visualizes India’s GDP in billion US dollars from 2009 to 2022 as a red line chart. The chart uses D3 v5 with SVG rendering, employing `scaleTime` and `scaleLinear` for axes, `axisBottom` and `axisLeft` with grid lines, and a `line` generator. Data is loaded from a CSV file via `d3.csv`, parsed with `new Date` and numeric conversion, then drawn in a centered group with margins, axis labels, and a title.
