Turn Spreadsheets into Graphviz Diagrams and AI-Ready Knowledge Graphs
The Relationship Visualizer spreadsheet transforms your Excel tables into clear, professional Graphviz diagrams in seconds. Say goodbye to manual drawing tools — simply enter your data as rows (e.g., "A is related to B"), and watch graphs appear automatically. That same data can also be exported as a structured Knowledge Graph in JSON, ready to hand to an AI tool instead of rendering as a picture.
Why Users Love It
Whether you're mapping data flows, organization charts, process workflows, timelines, or dependency diagrams, the Relationship Visualizer turns complex relationships into clear, expressive diagrams — or into a typed Knowledge Graph an AI can actually reason over.
