This bar chart displays the population of the top 10 most populous countries, using 2019 estimates from the United Nations World Population Prospects 2020. The visualization uses D3 v6 with an SVG rendering approach, employing `scaleLinear` for the x-axis and `scaleBand` for the y-axis. Data is loaded from a CSV file, with populations multiplied by 1000 to represent actual figures. The chart includes axes generated via `axisLeft` and `axisBottom`, with dark blue bars against a light blue background.
