This visualization shows the total number of dead and missing migrants per month, aggregated by year from the Missing Migrants Dataset. It renders as an SVG bar chart using React, where each bar represents the monthly sum of fatalities. The code uses d3.bin to create monthly time bins and d3.sum to aggregate the y-values within each bin, with d3.scaleTime and d3.scaleLinear mapping the data to screen coordinates. Hovering reveals exact totals via SVG title tooltips, while axis components from d3 handle tick generation and formatting.
