## 🚀 **Quick Start**

Get up and running with DataLineagePy in 30 seconds:

### Installation

```bash
# Install from PyPI (recommended)
pip install datalineagepy

# Or install from source
git clone https://github.com/Arbaznazir/DataLineagePy.git
cd DataLineagePy
pip install -e .
```

### Basic Usage

```python
from datalineagepy import LineageTracker, LineageDataFrame
import pandas as pd

# Initialize tracker
tracker = LineageTracker(name="my_pipeline")

# Create sample data
df = pd.DataFrame({
    'product_id': [1, 2, 3, 4, 5],
    'sales': [100, 200, 300, 400, 500],
    'region': ['North', 'South', 'East', 'West', 'Central']
})

# Wrap DataFrame for automatic lineage tracking
ldf = LineageDataFrame(df, name="sales_data", tracker=tracker)

# Perform operations - lineage is tracked automatically!
high_sales = ldf.filter(ldf._df['sales'] > 250)
regional_summary = high_sales.groupby('region').agg({'sales': 'sum'})

# Visualize the complete lineage
tracker.visualize()

# Export lineage data
tracker.export_lineage("my_pipeline_lineage.json")
```

**Result**: Complete data lineage tracking with zero configuration required!

## 🔧 **Usage Guide**

### Basic Operations

#### Creating a Lineage Tracker

```python
from datalineagepy import LineageTracker

# Basic tracker
tracker = LineageTracker(name="data_pipeline")

# Advanced configuration
tracker = LineageTracker(
    name="enterprise_pipeline",
    config={
        "memory_optimization": True,
        "performance_monitoring": True,
        "enable_validation": True,
        "export_format": "json"
    }
)
```

#### Working with DataFrames

```python
from datalineagepy import LineageDataFrame
import pandas as pd

# Create DataFrame
df = pd.DataFrame({
    'customer_id': [1, 2, 3, 4, 5],
    'order_value': [100, 250, 175, 320, 450],
    'region': ['US', 'EU', 'APAC', 'US', 'EU']
})

# Wrap for lineage tracking
ldf = LineageDataFrame(df, name="customer_orders", tracker=tracker)

# All pandas operations work normally
filtered = ldf.filter(ldf._df['order_value'] > 200)
grouped = filtered.groupby('region').agg({'order_value': ['sum', 'mean', 'count']})
sorted_data = grouped.sort_values(('order_value', 'sum'), ascending=False)
```

### Advanced Operations

#### Data Validation

```python
from datalineagepy.core.validation import DataValidator

# Setup validation
validator = DataValidator()

# Define validation rules
rules = {
    'completeness': {'threshold': 0.95},
    'uniqueness': {'columns': ['customer_id']},
    'range_check': {'column': 'order_value', 'min': 0, 'max': 10000}
}

# Validate data
results = validator.validate_dataframe(ldf, rules)
print(f"Validation score: {results['overall_score']:.1%}")
```

#### Analytics and Profiling

```python
from datalineagepy.core.analytics import DataProfiler

# Profile dataset
profiler = DataProfiler()
profile = profiler.profile_dataset(ldf, include_correlations=True)

print(f"Data quality score: {profile['quality_score']:.1f}")
print(f"Missing data: {profile['missing_percentage']:.1%}")
```

#### Custom Operations and Hooks

```python
# Define custom operation
def custom_transformation(data):
    """Custom business logic transformation."""
    return data.assign(
        order_category=lambda x: x['order_value'].apply(
            lambda val: 'High' if val > 300 else 'Medium' if val > 150 else 'Low'
        )
    )

# Register custom hook
tracker.add_operation_hook('custom_transform', custom_transformation)

# Use custom operation
result = ldf.apply_custom_operation('custom_transform')
```

### Export and Visualization

#### Generate Reports

```python
# Interactive HTML dashboard
tracker.generate_dashboard("lineage_report.html", include_details=True)

# Export lineage data
lineage_data = tracker.export_lineage()

# Multiple format export
tracker.export_to_formats(
    base_path="reports/",
    formats=['json', 'csv', 'excel']
)
```

#### Advanced Visualization

```python
from datalineagepy.visualization import GraphVisualizer

# Create visualizer
visualizer = GraphVisualizer(tracker)

# Generate different view types
visualizer.create_column_lineage_graph("column_lineage.png")
visualizer.create_operation_flow_diagram("operation_flow.svg")
visualizer.create_data_pipeline_overview("pipeline_overview.html")
```

### Performance Monitoring

```python
from datalineagepy.core.performance import PerformanceMonitor

# Enable performance monitoring
monitor = PerformanceMonitor(tracker)
monitor.start_monitoring()

# Your data operations here
result = ldf.complex_operations()

# Get performance summary
summary = monitor.get_performance_summary()
print(f"Average execution time: {summary['average_execution_time']:.3f}s")
print(f"Memory usage: {summary['current_memory_usage']:.1f}MB")
```
