diagram-as-code / cloud architecture diagrams
Diagrams is a Python library for drawing cloud system architecture diagrams as code, using Graphviz, for prototyping and version-controlling architecture designs.
Solves the same problem with a different architecture or at a different layer. Expect to rewrite the integration.
