About This Visualization

+

Data-Driven Styling: This globe uses Mapbox GL JS expressions to dynamically style 120+ countries based on economic indicators.

+

Expression Techniques: Interpolate expressions create smooth color gradients and proportional sizing based on data values.

+

Multi-Property Encoding: Each circle encodes two metrics simultaneously—size and color—revealing complex economic patterns.
