CartoDB is a platform for exploring and explaining data visually with new spatial and geospatial technologies. It allows users to access real-time data streams, perform geospatial algorithms to derive meaning from geographic data, and create custom visualizations, reports, and maps to share insights. CartoDB's tools like Torque enable animated and interactive web maps through techniques such as client-side rendering, tile-based data slicing, and delta encoding to optimize loading large datasets. Developers are encouraged to experiment with Torque's open source code and contribute new renderers and features.
