UML Class Diagram

A Unified Modeling Language (UML) Class diagram describes a system by visualizing the different types of objects within a system. JointJS, a JavaScript/Typescript diagramming library, can help users easily build this type of static diagram that describes the structure of a system. Using familiar SVG attributes, or custom JointJS properties, you will be able to visualize classes, their attributes, operations and relationships of a given system.

What is UML Class Diagram?

UML Class Diagrams are a powerful tool for developers to model the structure of their software systems. These diagrams depict the different classes that make up the system, along with their attributes and methods, and the relationships between them. With UML Class diagrams, developers can better understand the architecture of their code and how different parts of the system interact with each other.

As a JavaScript diagramming library provider, our product can be used to create UML Class diagrams in a user-friendly way, making it easier for developers to communicate and collaborate on their projects.
