The latest feature extends the Visual Editor to support direct interaction with class diagrams, offering users a variety of tools to enhance their diagramming experience.
In this blog post, we’ll walk you through the new features in the Mermaid Visual Editor, how to use them, and what changes have been made to streamline editing class diagrams. Let’s dive in!
What Are Class Diagrams?
Class diagrams are a type of UML (Unified Modeling Language) diagram used to model the structure of a system by showing its classes, attributes, methods, and the relationships between objects. They are a fundamental tool in object-oriented design and help visualize how different parts of a system interact with each other.
In a class diagram:
- Classes represent entities, such as objects or concepts.
- Attributes are the properties or characteristics of classes.
- Methods are the actions or operations that a class can perform.
- Relationships (e.g., associations, inheritance) show how classes are connected or interact.
Here’s an example of a basic Mermaid class diagram when rendered by Mermaid:
