This histogram shows the monthly count of dead and missing migrants from the Data Canvas Sense Your City subset, with reported dates on the x-axis and total fatalities on the y-axis. React renders an SVG with d3.scaleTime and d3.scaleLinear axes, while d3.bin groups the data into monthly thresholds and d3.sum aggregates the death counts per bin. Hovering over a bar reveals its exact total via a native SVG `<title>` tooltip.
