This example presents a line chart showing India’s population changes from 2010 to 2019. The visualization uses D3.js v6 with a React framework, rendering as an SVG. The chart reads data from a CSV file hosted on GitHub, converts year and population values to numbers, and uses `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for tick marks, and `d3.line` to draw the trend line. The SVG is appended to a styled HTML div.
