A horizontal bar chart displays the percentage of parliamentary seats held by women across world regions in 2019, ranging from roughly 4% in Melanesia to over 36% in Central America. The bars are rendered as SVG rectangles using D3’s `scaleLinear` and `scaleBand` for positioning, with axes generated via `axisLeft` and `axisBottom`. Data is loaded from a CSV file using `csv` and mapped to numeric values. The chart highlights regional disparities in gender representation, with the source attributed to the Inter-Parliamentary Union.
