## 🚀 Quick Start

### Installation

```bash
pip install network-visualization
```

That's it! No configuration needed.

### Usage in Your Script

**Option 1: Single import, one line**
```python
import network_visualization as nv

# Visualize (creates interactive HTML file)
nv.plot_network("path/to/your/calliope/model")
```

**Option 2: Complete analysis**
```python
import network_visualization as nv

# Analyze your model
results = nv.analyze_network("path/to/your/calliope/model")

# Check results
print(f"Network has {results['num_components']} components")
print(f"Isolated nodes: {results['isolated_nodes']}")
```

**Option 3: Copy-paste ready example**
```python
# Save this as visualize.py and run: python visualize.py
import network_visualization as nv

# Replace with your model path
MODEL_PATH = "C:/path/to/your/calliope/model"

# Create visualization
nv.plot_network(
    model_path=MODEL_PATH,
    output_file="my_network.html",
    title="My Energy Network"
)

print("✓ Visualization saved as my_network.html")
```

### Real Example with Your Model

```python
import network_visualization as nv

# Your model path (where locations.yaml is located)
model_path = "C:/Users/YourName/my_calliope_model"

# Option A: Quick visualization
nv.quick_viz(model_path)  # Opens in browser automatically

# Option B: Detailed analysis
analysis = nv.analyze_network(model_path)
print(f"Total locations: {analysis['total_nodes']}")
print(f"Total connections: {analysis['total_edges']}")
print(f"Network components: {analysis['num_components']}")
print(f"Isolated nodes: {analysis['isolated_nodes']}")
```

## 🌍 Advanced Features (v1.0.3)

### Multi-File Imports

The package now automatically resolves Calliope `import:` directives across multiple files:

```yaml
# model.yaml
import:
  - locations.yaml
  - techs.yaml

# locations.yaml
locations:
  region1:
    coordinates: {lat: 40, lon: -2}
```

**Usage:** Just point to your model - imports are handled automatically!

```python
nv.plot_network("path/to/model")  # Imports resolved automatically
```

### Scenarios

Apply Calliope scenarios to visualize different configurations:

```python
# Visualize with a specific scenario
nv.plot_network(
    model_path="path/to/model",
    scenario="high_cost",           # Apply 'high_cost' scenario
    title="High Cost Scenario"
)

# Analyze with scenario
results = nv.analyze_network(
    model_path="path/to/model",
    scenario="high_cost"
)
```

### Runtime Overrides

Apply custom overrides without modifying your model files:

```python
# Define overrides
overrides = {
    "locations.region1.coordinates.lat": 41.5,
    "locations.region1.coordinates.lon": -3.2,
    "links.region1,region2.distance": 150
}

# Visualize with overrides
nv.plot_network(
    model_path="path/to/model",
    override_dict=overrides,
    title="Modified Network"
)

# Combine scenario and overrides
nv.plot_network(
    model_path="path/to/model",
    scenario="high_cost",
    override_dict=overrides
)
```

### World Map Projection

All visualizations now use a world map with natural earth projection, perfect for global or multi-regional models.

## 🎯 Calliope Format Support

This package handles **any Calliope model structure**:

### Standard Format
```yaml
locations:
  region1:
    coordinates: {lat: 40, lon: -2}
    techs: {ccgt:, demand_power:}
```

### Split Coordinates
```yaml
locations:
  region1-1.coordinates:  # or region1:coords, region1_position, etc.
    lat: 41
    lon: -2
```

### Shared Technologies
```yaml
locations:
  "region1-1, region1-2, region1-3":  # or region1-1|region1-2|region1-3
    techs: {csp:}
```

### Any Coordinate System
- **Geographic**: `lat/lon`, `latitude/longitude`  
- **Cartesian**: `x/y`
- **Custom**: Any numeric coordinate pairs

### Flexible Naming
No restrictions on naming patterns:
- **Delimiters**: `.`, `:`, `_`, `-`, `|`, `,`
- **Suffixes**: `coordinates`, `coords`, `position`, `latlon`, etc.
- **Patterns**: Any naming convention (regions, nodes, stations, areas, etc.)

The parser automatically detects and handles all patterns!

## 📊 Example Output

### Visualization
Interactive HTML with:
- Color-coded nodes (generation, demand, transmission)
- Hover info showing technologies

## 🛠️ Requirements

- Python 3.8+
- All dependencies install automatically with `pip install network-visualization`

## ❓ Troubleshooting

### "Module not found"
```bash
# Make sure it's installed in your current environment
pip install network-visualization

# Check installation
pip show network-visualization
```

### "Can't find my model"
Make sure you point to the **model directory** (the folder containing `model_config/`):
```python
# ✓ Correct - points to model directory
nv.plot_network("C:/my_models/national_scale")

# ✗ Wrong - points to locations.yaml file
nv.plot_network("C:/my_models/national_scale/model_config/locations.yaml")
```

### Model structure requirements
Your Calliope model should have this structure:
```
your_model/
└── model_config/
    └── locations.yaml    # Required
```

### Import error in script
If you get import errors, use the full import:
```python
import network_visualization as nv
# Not: from network_visualization import plot_network
```

### Still having issues?
1. Check Python version: `python --version` (needs 3.8+)
2. Reinstall: `pip uninstall network-visualization && pip install network-visualization`
3. Try the simple example from `examples/simple_example.py`
