PlantUML

PlantUML is a versatile, open-source tool that allows you to create a wide range of diagrams from simple, text-based descriptions. This approach makes diagramming faster and more accessible.

Key Features:

• Text-to-Diagram: Effortlessly generate diagrams by writing simple descriptive text. This eliminates the need for complex graphical interfaces.
• Extensive Diagram Support: Create standard UML diagrams like sequence, use case, class, and activity diagrams. It also supports non-UML diagrams such as Gantt charts, mind maps, and network topologies.
• Multiple Export Options: Export your diagrams in various formats, including PNG, SVG, LaTeX, and EPS, ensuring compatibility with different documentation and presentation tools.
• Customization: Enhance your diagrams with features like notes, stereotypes, skins, and themes for a professional and personalized look.
• Integration: PlantUML can be integrated with various tools and environments, making it a flexible addition to your development workflow.

Supported Diagram Types:

• UML: Sequence, Use Case, Class, Activity, Component, State, Object, Deployment, Timing, Composite Structure, ER Diagram, C4 Diagram.
• Non-UML: Archimate, BPMN, Gantt, MindMap, WBS, JSON, YAML, Network, ASCII Art, Ditaa, Entity Relationship, Requirement.

Layout Engines:

PlantUML supports several layout engines, including Graphviz (default), Smetana, Viz.js, and ELK, allowing you to choose the best option for your diagram's complexity and desired appearance. It also offers different engines for sequence diagrams, such as Puma and Teoz, with Teoz providing advanced features like anchors and duration.

Output Formats:

Export your diagrams as PNG, SVG, LaTeX, EPS, and even text-based representations for sequence diagrams.
