This bar chart displays the population of various countries from a CSV dataset, using steel blue bars on a gray background. D3.js v7 loads the data via `d3.csv` and renders the visualization as SVG rectangles scaled with `d3.scaleBand` and `d3.scaleLinear`. Each bar includes a white text label above it showing the population value. The chart is fixed at 600 by 400 pixels within a styled container div.
