HyperGodot is an interactive, feature-rich visualization tool for hypergraphs, designed for advanced exploration and analysis of complex multi-actor relationships. Built using the Godot Engine, it supports dynamic layout computation, user customization, and comparative analysis through temporal or grouped hypergraphs.
- Multiple Layouts: Force-directed and circular layouts for vertex positioning.
- Convex Hull Edge Drawing: Uses Andrew’s monotone chain algorithm for rendering hyperedges with minimal overlap.
- Configurable Visualization:
- Define node sizes and edge widths using mathematical expressions.
- Adjustable point count for rendering smoothness.
- Edge and node coloring.
- Temporal and Grouped Hypergraph Support:
- Compare multiple hypergraph structures using groups and line styles (solid/dashed).
- Interactive UI:
- Drag to reposition nodes.
- Select node to filter visible edges.
- Camera controls for navigation and zoom.
Input hypergraphs are plain text files using a space-separated format per hyperedge. Each line defines a hyperedge and may include tags:
v1 v2 v3 #WEIGHT: 12 #GROUP: 2023
v4 v5 #WEIGHT: 8 #GROUP: 2022WEIGHT: numeric value representing edge weight (e.g., frequency, strength).
GROUP: label for grouping edges (e.g., year, category, temporal slice).
Users can customize the behavior and appearance of the visualization using a config file. Parameters include layout type, mathematical expressions for edge width and node size, and camera/export settings.
Example configuration:
[graph_settings]
point_count = 12
edge_width_expression = "weight * 0.2 + 1"
node_radius_expression = "30 + 100 * (centrality / total_nodes)"
layout = "force-directed"
parameters = [500, 250.0, 30.0]
