This stacked bar chart compares urban and rural population proportions across ten countries, with each horizontal bar segmented into two colored parts representing the population split. The visualization uses D3.js v7 with an SVG renderer, loading data from a CSV file and displaying percentages using a linear x-axis with percentage formatting. Hovering over a segment triggers a tooltip that reveals the precise percentage for that urban or rural population category. The chart includes a legend and axis labels, with colors assigned via a scaleOrdinal function using a two-color palette.
