This bar chart displays the population of the top 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects. The visualization uses D3’s `select` and `csv` to load data and render the chart. It customizes D3 axes with styled tick lines, tick text, and an axis label, while the CSS applies a steelblue fill to rectangles and adjusts font sizes for clarity. The title and axis annotations are positioned with D3’s selection methods, demonstrating a polished, readable bar chart.
