GraphRAG Parquet Visualizer
Simple parquet visualizer using html. Preferrably use artifacts folder to input parquet files, but you could easily browse your parquet files too. To remove demo data, click the “Clear Demo Data” at the bottom of the sidebar.

File Structure
artifacts/
├── your-graphrag-file1.parquet
├── your-graphrag-file2.parquet
└── other-parquet-files.parquet
Supported File Types
- Parquet files (.parquet): Standard Parquet files from GraphRAG
- CSV files (.csv): For testing or when Parquet files are not available
How It Works
- Place your Parquet files in this folder
- Open the visualizer HTML file
- Use the “Select Parquet Files” button to load your files
- Explore the interactive graph visualization
Notes
- The visualizer will automatically attempt to extract node and edge information from your files
- For best results, use Parquet files that follow the GraphRAG schema
- You can combine multiple files to create a comprehensive knowledge graph visualization
Example Files
If you don’t have your own files yet, you can use these example patterns for testing:
- Nodes should have unique IDs and descriptive properties
- Links should define source and target node IDs
- Including type information helps with visual categorization
Troubleshooting
If your files don’t visualize correctly:
- Verify they are valid Parquet/CSV files
- Check for required columns (id, source, target)
- Try a smaller subset of data first
