This bar chart displays the 2020 population of the top 13 most populous countries, sourced from Kaggle. Using D3 v7, the visualization renders population values as horizontal bars via SVG, with a linear scale for the x-axis and a band scale for the y-axis. The code employs `select`, `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to load data, compute scales, and draw axes.
