This chart aggregates monthly totals of dead and missing migrants from a global dataset. Bars represent the sum of recorded deaths and disappearances for each month, using a time series on the x-axis and a linear count on the y-axis. The visualization is built with React and D3 v7, using `d3.bin`, `d3.scaleTime`, and `d3.scaleLinear` to process and render the data as SVG rectangles. Tooltips reveal exact counts on hover.
