This bar chart displays the population of the top 10 most populous countries, using data from World Population Prospects 201. It shows population values on a linear x-axis with abbreviated tick labels (e.g., “B” for billions) and country names on a categorical y-axis. Built with D3 v5, the visualization uses `scaleLinear`, `scaleBand`, `axisBottom`, and `axisLeft` to render the chart as SVG, with gridlines and custom axis title formatting applied through the `format` API.
