jeetmarwah/diagrams — reverse-engineered prompt

Build me a Python library that lets someone draw cloud architecture diagrams by writing simple Python code instead of using a design tool. I want users to be able to create a diagram, add services like AWS, Azure, Google Cloud, Kubernetes, SaaS tools, programming languages, and on premise systems, connect them with arrows, group related parts, and export a clean image.

Please make it feel easy for a developer to install and use from a small script. It should use Graphviz or whatever is appropriate to render the final picture. Include a few example diagrams like an event processing system, a stateful app, and a web service with some on premise pieces.

This is only for drawing and documenting architecture, it should not create or manage any real cloud resources. Add basic tests, simple docs, and a nice quick start so someone can understand it fast. Look up current docs online if you need to.
