This histogram displays the total number of dead and missing migrants over time, with monthly bins aggregated from the Data Canvas Sense Your City dataset. The visualization uses React components for the axes and marks, with d3.scaleTime and d3.scaleLinear for scales. The data is loaded via d3.csv and processed using d3.histogram, d3.timeMonths, and d3.sum to create the bar chart rendered as SVG rectangles.
