This bar chart displays the population of the top 10 most populous countries, based on 2018 estimates from the United Nations World Population Prospects 2017. The chart uses a horizontal layout with a linear scale for population and a band scale for country names, styled with steel-blue bars. Rendered as SVG via d3.v5, the visualization includes axes with abbreviated tick labels (e.g., "1.4B") and a title. Data is loaded from a CSV file and parsed using d3.csv.
