This visualization shows the global rate of depression over time for each country, with a logarithmic y-axis displaying cumulative deaths. It uses React and d3.v5 to render an SVG line chart, with a Voronoi overlay for hover interactions that highlight the active country’s line and display a tooltip with exact values. Data comes from a CSV dataset processed via d3.csv, with scales and line generators built using d3.scaleTime, d3.scaleLog, and d3.line.
