This bar chart visualizes the monthly total number of dead and missing migrants over time, using a dataset from the Missing Migrants Project. The visualization processes incident records by binning them into monthly intervals with d3.bin, then summing the corresponding casualty values. Bars are rendered as SVG rectangles in React, with scales from d3.scaleTime and d3.scaleLinear positioning marks along the axes. Tooltips display the exact count per month via the SVG title element.
