This bar chart visualizes the ten most populous countries, displaying each nation's population as a vertical bar. The primary chart uses D3.js version 7, employing `scaleBand` for the x-axis and `scaleLinear` for the y-axis. It reads data from a CSV file containing population estimates for the year 2000, rendering the visualization as an SVG. The bars are styled in steel blue and change to orange on hover, with rotated x-axis labels for readability. The chart includes a responsive layout that adapts to its container's dimensions.
