This chart visualizes the top 10 most populous countries using a "pathetic" bar chart—bars extend horizontally from a left baseline without axes or ticks, though gridlines and x-axis labels are drawn. Built in React with D3 v5, it loads UN World Population Prospects 2019 data via `d3.csv`, scales the x-axis with `d3.scaleLinear` and y-axis with `d3.scaleBand`, and renders each bar as an SVG `<rect>`.
