Key features and capabilities of Sankey diagrams in GraphPolaris
Features
Sankey diagrams in GraphPolaris provide powerful tools for exploring and analyzing flow data.
Core Visualization Features
Proportional Flow Width
- Link width directly proportional to flow quantity
- Immediate visual comparison of relative magnitudes
- Consistent scaling across all flows
Multi-Level Node Layout
- Automatic positioning of nodes in columns
- Support for multiple intermediate stages
- Hierarchical and process-oriented layouts
Flow Tracing
- Clear visual paths from source to destination
- Smooth curved connections between nodes
- Color coding for flow categories or sources
Interactive Features
Hover & Highlight
- Hover over links to see exact flow values
- Highlight all flows through a specific node
- Trace complete pathways from source to sink
Node Manipulation
- Drag nodes to reorder within columns
- Collapse/expand node groups
- Focus on specific parts of the flow network
Filtering & Selection
- Filter by minimum flow threshold
- Show/hide specific flow categories
- Isolate pathways for detailed analysis
Analysis Features
Flow Metrics
- Total flow through each node
- Percentage of total for each link
- Net flow calculations (in vs out)
Loss Detection
- Automatic calculation of flow differences
- Highlight stages with significant loss
