A choropleth world map visualizes the Equaldex 2025 data, showing each country's legal and public opinion equity indices. Users hover over countries to reveal a tooltip with the country's index scores, population, and GDP. The visualization uses D3.js v5 with an AuthaGraph projection, `d3.geoPath`, zoom behavior, and color scales to render the map. A toggle button switches between displaying legal and opinion-based data, with an animated legend that updates accordingly.
