This bar chart displays the app's top 10 most populous countries, with each bar showing estimated population from 2018 data accessed via a CSV file. The visualization uses D3 v5’s `scaleLinear` and `scaleBand` to map numeric values and categorical labels, while `axisBottom` and `axisLeft` render customized axes with tick formatting that converts large numbers to abbreviated labels. Data is loaded asynchronously with `csv` from D3, and the SVG output is rendered without any additional framework.
