Features

Semantic substrates in GraphPolaris provide powerful tools for attribute-driven network exploration.

Core Visualization Features

Attribute-Based Regions

• Define regions by categorical attributes (type, category, department)
• Use continuous attributes for axis positioning (time, value, rank)
• Combine attributes for 2D region grids
• Custom region shapes and layouts

Meaningful Node Placement

• Node position encodes attribute values
• Consistent positioning aids comparison and memory
• Optional secondary attribute for within-region ordering
• Jittering to avoid overlap while preserving meaning

Edge Rendering

• Clear visualization of within-region and cross-region edges
• Edge bundling to reduce clutter
• Optional edge filtering by type or weight
• Curved edges for better visual tracing

Interactive Features

Region Configuration

• Drag to resize and reposition regions
• Show/hide specific regions
• Reorder regions for different perspectives
• Collapse regions to summarize

Node Exploration

• Click nodes to see details and connections
• Highlight all edges from selected node
• Filter to show only connected nodes
• Search and locate specific nodes

Edge Filtering

• Show/hide within-region edges
• Show/hide cross-region edges
• Filter by edge weight or type
• Progressive disclosure of complexity

Analysis Features

Cross-Region Metrics

• Count of edges between each region pair
• Density comparison across regions
• Bridge node identification
• Community detection within regions

Attribute Correlation

• See how network structure relates to attributes
• Identify homophily patterns
• Detect attribute-based clustering
• Compare connectivity by attribute value

Temporal Analysis

• Time-based region arrangement
• Track network evolution across periods
• Animate changes over time
• Compare snapshots

Layout Options

Region Types

• Grid layout: Rows and columns for two attributes
• Parallel regions: Side-by-side comparison
• Nested regions: Hierarchical attribute structure
• Radial regions: Categories around a center

Within-Region Layout

• Random with jittering
• Attribute-based positioning
• Force-directed within bounds
• Grid or list arrangement

Customization

• Region colors and labels
• Node sizing by attribute
• Edge styling by type
• Background annotations

Data Support

Input Requirements

• Network with node attributes
• At least one categorical or ordinal attribute
• Edge list with optional attributes

Attribute Types

• Categorical (department, type, category)
• Ordinal (rank, level, stage)
• Temporal (date, period, year)
• Continuous (for axis positioning)

Multi-Attribute Support

• Primary attribute for regions
• Secondary attribute for within-region position
• Additional attributes for visual encoding

Export & Sharing

• Export static images (PNG, SVG)
• Export region statistics
• Save region configurations
• Share interactive views
