This example presents a world map visualization focused on economic data, embedding an interactive map created with CartoDB’s builder interface. The page uses d3.v4 to load and structure the environment, but the core rendering is handled by an external iframe that pulls from a Carto map. The visualization displays geographic regions with economic indicators, allowing users to explore the data through Carto’s interactive mapping tools. The code relies on d3’s selection and utility functions for DOM setup, while the primary map rendering occurs outside d3’s native drawing capabilities.
