Build authentication and REST API flows with PlantUML participants, messages, activation bars, conditions, loops, and numbering.
Build a PlantUML class diagram with fields, methods, visibility, inheritance, interfaces, dependency, aggregation, composition, and multiplicity.
Create a PlantUML ER diagram with entities, keys, required attributes, and crow's-foot cardinality, and compare IE, Chen, and class diagram notation.
Create PlantUML C4 diagrams for system context, containers, and components using C4-PlantUML macros, reproducible includes, and a connected example.
Learn how to style PlantUML diagrams with named colors, hex values, built-in themes, CSS-like styles, and accessible color choices.
