A stacked bar chart displays monthly mortality counts from the Crimean War, broken down by cause—disease, wounds, and other—using a dataset from a TSV file. The chart uses an ordinal x-axis with rounded bands and a linear y-axis, with layers computed via `d3.layout.stack`. SVG rectangles represent each cause per month, colored by a category scale. Formatting relies on `d3.time.format` for date parsing and axis tick labels, with axes generated through `d3.svg.axis`.
