This responsive bar chart displays estimated state populations using horizontal bars, with each bar’s length proportional to visitor counts. It first renders a gray inner rectangle behind the plot area, then draws axes and labels using `d3.scaleLinear` and `d3.scaleBand`. The chart adapts to container resizing via `observeResize` and `@curran/responsive-axes`, while data originates from the `@curran/un-population-estimates-2024` module.
