This horizontal bar chart visualizes the female percentage of total population for selected countries in 2018. The chart uses a linear scale for population values and a band scale for country labels, with axis functions `axisLeft` and `axisBottom` generating the grid. Data is loaded from a CSV using `d3.csv`, and each bar is rendered as an SVG rectangle. The source is World Bank staff estimates based on United Nations Population Division data, styled with forest green fills.
