This bar chart displays the population of the world's ten most populous cities, sorted by metropolitan population in descending order, using data from `worldData.csv`. The chart is rendered using D3.js, specifically employing `scaleLinear` and `scaleBand` for the x and y axes, with `axisBottom` and `axisLeft` to generate the axes. The visualization is built by creating rectangles for each bar, with a pink background and steelblue bars, and includes formatted axis labels and a title.
