Fireworks Tech Graph — AI-Powered Technical Diagram Generator

Introduction

Fireworks Tech Graph is an open-source Python tool that converts natural language descriptions into production-quality SVG and PNG technical diagrams. It supports multiple visual styles and diagram types including UML, system architecture, flowcharts, and AI/agent workflow patterns.

What Fireworks Tech Graph Does

• Generates SVG and PNG diagrams from plain text descriptions
• Supports 7 distinct visual styles for different contexts
• Creates UML diagrams including sequence, class, and state diagrams
• Produces AI agent workflow and pipeline visualizations
• Exports in scalable vector format suitable for documentation and presentations

Architecture Overview

The tool is built in Python and uses LLM-powered interpretation to parse natural language into structured diagram definitions. It then renders these definitions using SVG primitives with precise layout algorithms. The rendering engine handles node positioning, edge routing, and style application independently of the AI interpretation layer.

Self-Hosting & Configuration

• Install via pip with Python 3.9 or higher
• Configure your preferred LLM API key for text interpretation
• Set default output format (SVG or PNG) and resolution
• Choose from built-in style presets or customize colors and fonts
• Integrate into CI pipelines for automated documentation diagrams

Key Features

• Natural language to diagram conversion with minimal prompting
• Seven visual styles from minimal to detailed technical
• UML support covering common software design patterns
• AI/agent workflow patterns for documenting LLM pipelines
• High-quality vector output suitable for technical documentation

Comparison with Similar Tools

• Mermaid — code-based diagram syntax, requires learning specific markup
• PlantUML — powerful but verbose DSL, steeper learning curve
• Excalidraw — manual drawing tool, not text-to-diagram
• D2 — declarative diagram language, not natural language driven
• tldraw — canvas SDK for building diagram tools, not a generator

FAQ

Q: Which LLM providers are supported? A: The tool works with OpenAI, Anthropic, and other providers that expose a compatible API.

Q: Can I use it without an API key? A: The diagram generation requires an LLM for interpretation. Check documentation for local model options.

Q: What diagram types are supported? A: Architecture diagrams, UML (sequence, class, state), flowcharts, and AI workflow patterns.

Q: Can I customize the visual style? A: Yes. Choose from 7 built-in styles or define custom color palettes and typography.
