This histogram displays the monthly total of dead and missing migrants from the Data Canvas Sense Your City Dataset. The chart aggregates individual incident records into monthly bins, with bar heights representing the summed death toll per month. Built with React and D3 v5, the visualization uses `d3.histogram` for binning, `d3.scaleTime` and `d3.scaleLinear` for axes, and renders interactive SVG rectangles with native tooltips. The axes, formatted with `d3.timeFormat`, clearly show temporal trends in the data.
