This visualization combines a world choropleth map with a scatter plot to explore cat breed data from Kaggle. The map uses `d3.geoEqualEarth` projection with `d3.geoPath` to render geographic boundaries, colored by the count of breeds per country using a `scaleThreshold` color scale. The scatter plot displays maximum life expectancy against minimum weight, with scatter points sized by a computed attribute. Both SVG panels render in React, with an HTML tooltip for interactivity. The visualization is built with d3.v6 and includes animated transitions between views.
