This histogram visualizes the monthly total of dead and missing migrants, using data from the Missing Migrants Dataset. The React application loads the data via `d3.csv` and displays the counts as vertically positioned rectangles. The visualization uses D3 v5's `scaleTime`, `histogram` (via `bin()`), and `sum` to aggregate the data by month, with axes rendered as SVG elements. Time is shown on the x-axis, and the counts are on the y-axis, with a tooltip revealing the exact sum for each bar.
