This histogram shows the monthly aggregate total of dead and missing migrants worldwide, with bars representing cumulative deaths per month over time. The visualization uses React to manage state and D3 v5's `scaleTime`, `scaleLinear`, `histogram`, and `timeMonths` APIs to bin the data by calendar month and compute the sum of deaths per bin. The data comes from a subset of the Missing Migrants Global dataset, loaded via `d3.csv`, and is rendered as SVG rectangles with tooltips showing exact totals.
