This visualization links a choropleth map of cat breed origins with a scatter plot of their physical traits. It displays the geographic distribution of cat breeds by country, alongside a plot of their maximum life expectancy against minimum weight. The code uses `d3.geoEqualEarth` and `d3.geoPath` to render the map, while `d3.scaleThreshold` maps the count of breeds to a color scale. The scatter plot uses `d3.extent` to determine axis domains, with the data sourced from the Kaggle cat breeds dataset.
