This visualization displays the total number of dead and missing migrants over time, aggregated into monthly bins using d3.histogram and d3.timeMonths. The bar chart shows the data from the Data Canvas Sense Your City Dataset, with time on the x-axis and casualty counts on the y-axis. React renders SVG elements including custom AxisBottom, AxisLeft, and Marks components, while d3.scaleTime, d3.scaleLinear, and d3.sum handle the data processing and scaling.
