When to Use This Skill
USE AutoViz when:
- Quick EDA - Need rapid insights into a new dataset
- Initial exploration - Starting analysis on unfamiliar data
- Pattern discovery - Automatically detect relationships between variables
- Presentation prep - Need charts quickly for stakeholder meetings
- Large datasets - Built-in sampling handles big data efficiently
- Feature analysis - Understanding distribution and importance of features
- Correlation hunting - Finding relationships without manual chart creation
- Report generation - Export comprehensive HTML reports
DON'T USE AutoViz when:
- Custom visualizations - Need highly specific chart designs
- Interactive dashboards - Use Streamlit or Dash instead
- Real-time data - Streaming visualization requirements
- Production systems - Charts for automated pipelines (use Plotly/Altair)
- Precise statistical tests - Need formal hypothesis testing
- Domain-specific plots - Specialized visualizations not in standard EDA
Prerequisites
# Basic installation
pip install autoviz
# With all visualization backends
pip install autoviz matplotlib seaborn plotly bokeh
# Using uv (recommended)
uv pip install autoviz pandas matplotlib seaborn plotly
# Jupyter notebook support
pip install autoviz ipywidgets notebook
# Verify installation
python -c "from autoviz import AutoViz_Class; print('AutoViz ready!')"
