This bar chart displays the top 10 most populous countries as of January 2024, with bar length representing population in thousands. It uses d3.scaleBand and d3.scaleLinear for positioning, while mouseenter and mouseleave events trigger state updates that dim non-hovered bars to gray. The visualization loads population data from the @curran/un-population-estimates-2024 package and uses @drbagwell/responsive-viz-axes for responsive sizing and axis rendering.
