# 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
