This bar chart displays the population of the top 10 most populous countries, with horizontal bars sorted by country name. The visualization uses D3 v5’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to map population values and country labels. Data is loaded from a local CSV file and rendered as SVG rectangles, with axis tick labels formatted using D3’s `format` function. The chart includes a title, axis label, and gridlines via `tickSize`.
