Understanding GIS Data Layers: Basemap, Polygon, and Bubble Visualization #3254227 (License: Personal Use)

This isometric diagram demonstrates a multi-layered Geographic Information System (GIS) structure, where a colored basemap forms the foundation, overlaid by two polygon layers representing geographic boundaries or zones, and a bubble layer visualizing point-based quantitative data (e.g., population or sales). Green arrows at the top suggest data processing, aggregation, or user interaction between layers. The design emphasizes hierarchical data integration and dynamic spatial analysis.

Used in GIS tutorials, cartography guides, or software documentation (e.g., ArcGIS, QGIS, Mapbox) to explain layering concepts, data symbology, and interactive mapping workflows. Matches user intent for learning spatial data organization or designing layered web maps.
