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
  • Conservation checking for closed systems

Path Analysis

  • Identify dominant pathways
  • Calculate path-specific totals
  • Compare alternative routes

Layout Options

Automatic Layout

  • Optimal node positioning for readability
