ndiag

ndiag is a "high-level architecture" diagramming/documentation tool.

Key features of ndiag are:

• N-diagrams: Generate multiple "diagrams and documents" (views) from a single configuration.
• Nested-clusters: Nodes and components can be clustered in nested layers
• Provides the ability to check the difference between the architecture and the actual system.

Usage

$ ndiag doc -c ndiag.yml --rm-dist
