Key features and capabilities of Map Visualizations in GraphPolaris
Features
Map visualizations in GraphPolaris provide powerful tools for geographic network exploration.
Core Visualization Features
Node Overlays
- Markers positioned at geographic coordinates (latitude/longitude)
- Multiple marker styles (circles, icons, custom shapes)
- Size encoding for node attributes (value, degree, importance)
- Color encoding for categories or continuous values
- Marker clustering for dense regions
Edge Overlays
- Lines connecting geographic locations
- Straight lines or great circle arcs for long distances
- Width encoding for edge weight or flow volume
- Color encoding for edge type or direction
- Opacity control for dense edge networks
Base Map Options
- Street maps for urban context
- Satellite imagery for physical geography
- Terrain maps for topographic context
- Minimal/dark themes for data focus
- Custom tile sources
