This visualization displays the total number of dead and missing migrants each month, using data from the Missing Migrants Dataset. The bar chart's x-axis represents time, while the y-axis shows the average age at death, with each bar's height corresponding to the mean age for that month. Built with React and rendered as SVG, the code uses d3's `bin` function to aggregate data into monthly intervals and `mean` to calculate the average age, with axes and marks handled by custom components.
