A histogram displays the monthly total of dead and missing migrants from the Data Canvas Sense Your City dataset, with time on the x-axis and death counts on the y-axis. Using React and D3 v5, the code employs `d3.bin` and `d3.timeMonths` to aggregate reported dates, while `d3.scaleTime` and `d3.scaleLinear` map the data to SVG rectangles. Hovering reveals the exact count via a native `<title>` tooltip.
