This chart visualizes the total number of dead and missing migrants over time, using a bar chart with an overlaid line to show the trend. The data is binned into monthly intervals using D3’s `bin` and `timeMonths` functions, with bar heights representing the monthly sum and a natural curve line connecting the values. Built with React and D3 v6, it uses `scaleTime` and `scaleLinear` for axes, rendered as an SVG with custom axis components. The tooltip on each bar displays the exact monthly total.
