Stacked Bar Category Comparison with Horizontal Trend Line

Stacked percent bar-line graphs combine features of stacked bar charts and line graphs. The bars represent parts of a whole, with each segment showing a percentage contribution to the total. The stacked format makes it easy to compare proportions across categories. Meanwhile, the line overlay can track trends or other related data points across the same categories, offering a dual-layered visualization.
