Data Flow Tool

A modern data lineage visualization tool that helps you understand column-level dependencies between your data tables.

Features

• Interactive visualization of data lineage
• Column-level dependency tracking
• Support for DBT projects
• Dark/Light mode
• Interactive column highlighting
• Draggable nodes
• Detailed tooltips with metadata

Installation

pip install dataflowtool

Usage

1. From the command line:

dataflowtool

This will start the server and open the visualization in your default web browser.

DBT Integration

The tool automatically detects DBT projects in the current directory or its parents. If a DBT project is found, it will use the manifest.json and catalog.json files to generate the lineage visualization.

If no DBT project is found, the tool will use sample data to demonstrate its functionality.
