Graphviz DOT Renderer Skill

Overview

Renders Graphviz DOT graph definitions to images supporting multiple layout algorithms for dependency visualization and large graph rendering.

Capabilities

• Render DOT graphs to PNG, SVG, PDF, PS formats
• Multiple layout algorithms (dot, neato, fdp, sfdp, twopi, circo)
• Large graph support with sfdp algorithm
• Dependency visualization
• Custom node and edge styling
• Subgraph and cluster support

Target Processes

• microservices-decomposition
• ddd-strategic-modeling
• observability-implementation
