This example shows estimated population data for Indian states and territories in 2019, displaying the last ten entries as a horizontal bar chart. The bars are rendered as SVG rectangles using D3 v6, with their widths scaled by a linear scale (`d3.scaleLinear`) mapping population values to pixel space. The data is loaded asynchronously from a CSV file via `d3.csv` from a GitHub gist, and the chart dimensions adapt to the browser window size. The code uses `d3.select`, `d3.extent`, and Promise-based async/await to handle data loading and rendering.
