This bar chart displays population estimates for the ten most populous countries, using horizontal bars ordered alphabetically by country name. The visualization loads data from a CSV file and renders it as SVG rectangles. It employs D3 v4’s `scaleLinear` for the population axis, `scaleBand` for categorical country positioning, and `axisLeft`/`axisBottom` to generate the chart’s axes. Population values are parsed and multiplied by 1,000 to reflect actual counts from the source data.
