# Sweetviz

## When to Use This Skill

### USE Sweetviz when:

- **Dataset comparison** - Comparing train vs test, before vs after, or any two datasets
- **Target variable analysis** - Understanding how features relate to a target
- **Quick EDA reports** - Need comprehensive EDA in one line of code
- **Feature comparison** - Analyzing feature distributions across subsets
- **HTML reports** - Creating shareable, interactive analysis reports
- **Intra-set analysis** - Comparing subpopulations within a dataset
- **Data validation** - Checking for data drift between datasets
- **Feature selection** - Identifying important features for modeling
### DON'T USE Sweetviz when:

- **Very large datasets** - Over 1M rows (use sampling)
- **Streaming data** - Need real-time analysis
- **Deep statistical tests** - Need p-values and hypothesis testing
- **Custom visualizations** - Specific chart requirements
- **Interactive dashboards** - Use Streamlit or Dash instead
- **Text/NLP analysis** - Use dedicated NLP tools

## Prerequisites

```bash
# Basic installation
pip install sweetviz

# Using uv (recommended)
uv pip install sweetviz pandas numpy

# With Jupyter support
pip install sweetviz pandas numpy jupyter

# Verify installation
python -c "import sweetviz as sv; print(f'Sweetviz version: {sv.__version__}')"
```
### System Requirements

- Python 3.6 or higher
- pandas 0.25.3 or higher
- numpy
- matplotlib (for internal plotting)
- Modern web browser (for viewing HTML reports)

## Complete Examples

### Example 1: ML Dataset Profiling Pipeline

```python
#!/usr/bin/env python3
"""ml_profiling_pipeline.py - Complete ML dataset profiling with Sweetviz"""

import sweetviz as sv
import pandas as pd
import numpy as np
from sklearn.model_selection import train_test_split
from datetime import datetime
import os

*See sub-skills for full details.*
### Example 2: Data Quality Assessment

```python
#!/usr/bin/env python3
"""data_quality_assessment.py - Data quality assessment with Sweetviz"""

import sweetviz as sv
import pandas as pd
import numpy as np
from datetime import datetime
import os
import json

*See sub-skills for full details.*
### Example 3: Feature Selection Analysis

```python
#!/usr/bin/env python3
"""feature_selection_analysis.py - Feature analysis for ML with Sweetviz"""

import sweetviz as sv
import pandas as pd
import numpy as np
from sklearn.model_selection import train_test_split
import os
