This bar chart displays the population of the top 10 most populous countries, using 2018 estimates from World Population Prospects 2017. The visualization loads data from a CSV file and renders it as an SVG, with the y-axis ordered by country name and the x-axis scaled linearly. The code uses D3 v5 modules including `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to build the chart, apply margins, and add axis labels. Population values are converted from thousands to full counts, and the x-axis ticks use a custom formatter to abbreviate large numbers.
