This interactive D3.js visualization argues for universal healthcare by correlating national happiness rankings with suicide rates across selected countries. Users explore a choropleth map, built with `d3.geoPath` and `d3.geoProjection`, to hover over countries and reveal metrics like happiness rank, suicides per 1000 population, healthcare access, median salary, and poverty rate. Accompanying bar charts and scatter plots, rendered with standard D3 scales, allow toggling between healthcare systems to compare these relationships. The analysis is based on country-level data presented through a static HTML interface with CSS styling.
