A bar chart displays population estimates for eight countries in 2017, using a vertical layout with country names on the y-axis and population values on the x-axis. The visualization reads population data from a CSV file and renders it as SVG rectangles using D3 v5’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` APIs. The chart applies a steelblue fill to the bars, with axes generated through D3’s axis components.
