+## Network Visualization
+
+The NetBird Python client includes powerful network visualization capabilities that can generate topology diagrams in multiple formats:
+
+### Generate Network Maps
+
+```python
+from netbird import APIClient, generate_full_network_map
+
+# Initialize client
+client = APIClient(host="your-netbird-host.com", api_token="your-token")
+
+# Generate enriched network data
+networks = generate_full_network_map(client)
+
+# Access enriched data
+for network in networks:
+    print(f"Network: {network['name']}")
+    for resource in network.get('resources', []):
+        print(f"  Resource: {resource['name']} - {resource['address']}")
+    for policy in network.get('policies', []):
+        print(f"  Policy: {policy['name']}")
+```
+
+### Topology Visualization
+
+```python
+from netbird import get_network_topology_data
+
+# Get optimized topology data for visualization
+topology = get_network_topology_data(client, optimize_connections=True)
+
+print(f"Found {len(topology['all_source_groups'])} source groups")
+print(f"Found {len(topology['group_connections'])} group connections")
+print(f"Found {len(topology['direct_connections'])} direct connections")
+```
+
+### Diagram Generation
+
+Use the included unified diagram generator to create visual network topology diagrams:
+
+```bash
+# Set your API token
+export NETBIRD_API_TOKEN="your-token-here"
+
+# Generate Mermaid diagram (default, GitHub/GitLab compatible)
+python unified-network-diagram.py
+
+# Generate Graphviz diagram (PNG, SVG, PDF)
+python unified-network-diagram.py --format graphviz
+
+# Generate Python Diagrams (PNG)
+python unified-network-diagram.py --format diagrams
+
+# Custom output filename
+python unified-network-diagram.py --format mermaid -o my_network_topology
+```
+
+### Supported Diagram Formats
+
+| Format | Output Files | Best For |
+|--------|-------------|----------|
+| **Mermaid** | `.mmd`, `.md` | GitHub/GitLab documentation, web viewing |
+| **Graphviz** | `.png`, `.svg`, `.pdf`, `.dot` | High-quality publications, presentations |
+| **Diagrams** | `.png` | Code documentation, architecture diagrams |
+
+### Diagram Features
+
+- **Source Groups**: Visual representation of user groups with distinct colors
+- **Networks & Resources**: Hierarchical network structure with resource details
+- **Policy Connections**: 
+  - 🟢 **Group-based access** (dashed lines)
+  - 🔵 **Direct resource access** (solid lines)
+- **Optimized Layout**: Merged connections to reduce visual complexity
+- **Rich Information**: Resource addresses, types, and group memberships
+
+### Installation for Diagrams
+
+```bash
+# For Graphviz diagrams
+pip install graphviz
+
+# For Python Diagrams
+pip install diagrams
+
+# Mermaid requires no additional dependencies
+```
