This bar chart displays the population of nine South Asian countries, sorted by country name, with population values in thousands. The visualization uses D3 v6 with SVG rendering, employing `d3.csv` to load the data, `scaleLinear` and `scaleBand` for the x and y axes, and `axisLeft` and `axisBottom` for ticks. The chart applies a custom tick format to abbreviate large numbers and includes a population axis label.
