This stacked bar chart visualizes the distribution of education levels among female and male groups, showing the proportion of each subgroup within each gender. The code uses D3 v7 to load CSV data, stack the categories with `d3.stack()`, and render the results as SVG rectangles. A color scale maps each education level to a distinct color, while an axis is added using `d3.axisBottom` and `d3.axisLeft`. The visualization emphasizes the relative composition of educational backgrounds across the two gender groups.
