This line chart visualizes the population of India from 1999 to 2012, with time on the x-axis and population values on the y-axis. The chart is rendered in an SVG element using D3 v5 within a React framework, with data loaded from a CSV file via `d3.csv`. The visualization uses `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.line` to construct the axes, line path, and labels, all styled through an external CSS file.
