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. It uses D3 v5 to load the data via `d3.csv` and renders bars as SVG rectangles. The visualization demonstrates customized axes, including a formatted x-axis that abbreviates large numbers and removes gridlines, while the y-axis hides its line and tick marks. The chart also annotates its title and axis label directly within the SVG.
