This example visualizes the top 10 most populous countries as a set of unlabeled, uncoordinated bars using a pathetic bar chart with no axes or scales displayed. It loads population data from the United Nations World Population Prospects 2019 dataset via `d3.csv`, then maps each country to a rectangle using React and D3’s `scaleBand` and `scaleLinear` for positioning. The SVG rendering shows raw bar widths proportional to population, with no gridlines, ticks, or labels, emphasizing the data’s bare presentation.
