Particle Physics Tutorial

Demonstrates network-based approaches to computational physics:

from graphizy import Graphing, generate_and_format_positions

# Generate particle configuration
particles = generate_clustered_particles(150, box_size=(600, 600))

# Analyze percolation behavior
grapher = Graphing()
graph = grapher.make_graph("proximity", particles, proximity_thresh=30.0)
result = grapher.get_graph_info(graph)

# Use advanced percolation analysis
ranges = [15, 20, 25, 30, 35, 40, 45]
percolation = result.percolation_analyzer.analyze_percolation_threshold(
    particles, ranges
)

print(f"Critical threshold: {percolation.critical_range}")

# Detect phase transition
transition = result.percolation_analyzer.detect_phase_transition(percolation)
print(f"Transition detected: {transition['has_transition']}")

Key Features: - Automated critical threshold detection - Phase transition characterization - Cluster formation analysis - Temporal evolution tracking

Animal Behavior Tutorial

Analyzes social dynamics in animal groups:

# Simulate animal movement over time
trajectory = simulate_herd_movement(num_animals=20, timesteps=30)

# Analyze social networks
graph_sequence = []
for positions in trajectory:
    graph = grapher.make_graph("proximity", positions, proximity_thresh=120.0)
    graph_sequence.append(graph)

# Identify social roles
result = grapher.get_graph_info(graph_sequence[0])
social_analyzer = result.social_analyzer

# Track roles over time
temporal_roles = social_analyzer.track_temporal_roles(graph_sequence)
stability = social_analyzer.get_role_stability(temporal_roles)

# Find consistent leaders
bridges = [animal for animal, data in temporal_roles.items()
          if 'bridge' in data['roles'][0]]
print(f"Social bridges identified: {bridges}")

Key Features: - Social role classification (bridge, hub, peripheral) - Temporal role stability analysis - Leadership pattern detection - Group dynamics visualization

Urban Planning Tutorial

Evaluates spatial accessibility and service coverage:

# Generate urban features
residential = generate_residential_areas(300)
schools = generate_service_locations(12, "school")
hospitals = generate_service_locations(4, "hospital")

# Analyze accessibility
result = grapher.get_graph_info(base_graph)
accessibility_analyzer = result.accessibility_analyzer

# School accessibility analysis
school_access = accessibility_analyzer.analyze_service_accessibility(
    residential, schools, "school", service_distance=400.0
)

print(f"School coverage: {school_access.get_coverage_percentage():.1f}%")
print(f"Equity score: {school_access.get_equity_score():.3f}")

# Identify service gaps
gaps = accessibility_analyzer.identify_service_gaps(school_access)
print(f"Service gaps: {len(gaps)}")

Key Features: - Service coverage calculation - Spatial equity assessment - Service gap identification - Comparative analysis tools

Real-World Applications

Paramecium Population Analysis

Graphizy provides specialized tools for studying topological interactions in microbial communities:

# Real-time analysis of Paramecium populations
def analyze_paramecium_swarm(tracking_data):
    """
    Analyze collective behavior in Paramecium populations

    tracking_data: Real-time position data from microscopy
    """
    grapher = Graphing()
    grapher.init_memory_manager(max_memory_size=200, track_edge_ages=True)

    temporal_networks = []
    for frame_data in tracking_data:
        # Create proximity network
        graph = grapher.make_graph("proximity", frame_data,
                                 proximity_thresh=50.0)  # 50 micrometers

        # Update memory for temporal analysis
        grapher.update_memory_with_graph(graph)
        temporal_networks.append(graph)

    # Analyze swarm dynamics
    result = grapher.get_graph_info(temporal_networks[-1])

    # Social structure analysis
    roles = result.social_analyzer.track_temporal_roles(temporal_networks)

    # Percolation behavior
    percolation = result.percolation_analyzer.analyze_percolation_threshold(
        tracking_data[-1], [20, 30, 40, 50, 60]
    )

    return {
        'social_structure': roles,
        'percolation_behavior': percolation,
        'temporal_networks': temporal_networks
    }

This enables researchers to: - Study collective behavior patterns in real-time - Perturb swarm dynamics and observe responses - Identify key individuals driving group behavior - Track topological changes during collective motion

# Convert analysis results to DataFrame
df = pd.DataFrame([
    {
        'node_id': node_id,
        'role': role.roles[0] if role.roles else 'regular',
        'betweenness': role.stats['betweenness'],
        'degree': role.stats['degree']
    }
    for node_id, role in social_roles.items()

# High-quality visualizations for papers
grapher.update_config(drawing={
    "point_radius": 8,
    "line_thickness": 2,
    "point_color": (100, 150, 255),
    "line_color": (255, 100, 100)
})

# Create memory-enhanced visualization
memory_graph = grapher.make_memory_graph(data)
image = grapher.draw_memory_graph(memory_graph,
                                use_age_colors=True,
                                alpha_range=(0.3, 1.0))
