Understanding the architecture of a software system is crucial for successful development and maintenance. Once you understand how your system fits in to the overall IT environment, a really useful next step is to zoom-in to the system boundary with a Container diagram. 📄 C4-PlantUML; 📄 Layout Options; 📄 Themes (different styles and languages) samples 📄 C4 Model Relationship Between C4 Model and C4 Diagram The C4 Model is a framework for visualizing the architecture of a software system. Modelling is the act of describing your system. Each diagram type visualizes the abstractions for each of the C4 levels. and paste a screen shot into our wiki docs or have tried to use PlantUML. Creating C4 Model Diagrams with CodeSee. 1️⃣ Level 1 — Context diagram. The final level of diagram in the C4 model is the “code” diagram”, which is fundamentally just a class diagram from UML. C4 is a standardized model to visualize software architecture. It is particularly useful for developers who need to work on or 2️⃣ 4 diagram types. The C4 model allows representing a software system with a set of diagrams, each describing in depth a different level of detail. The Model DSL is implemented in Go and follows the C4 Model to describe the software architecture. sfbkag lhh pcl sprf jrdk yjuje kbwvyc hxjuyp ynrmb jri
