The visualization displays the total dead and missing migrants over time on a logarithmic y-axis, with each circle representing a report date. Time runs along the x-axis via d3.scaleTime, while d3.scaleLog compresses the wide range of person counts. React components render SVG circles wrapped in d3.v7 scales, with axis components formatting ticks and a tooltip showing the full date. Data comes from a CSV file loaded asynchronously via d3.csv in a custom useData hook.
