This visualization displays the total number of dead and missing migrants over time, aggregated by month from the Data Canvas Sense Your City dataset. React with D3 v5 renders an SVG bar chart using `d3.histogram` to bin the data, `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.sum` to aggregate values per month. The bars show monthly totals, with axes labeled and styled using CSS.
