These features are present in any sequence diagram we’ll look at interactive AppMap capabilities in a later section.

Let’s talk about the basic features of a sequence diagram. Documentation: Sequence diagrams can be used to document the design and behavior of a system, providing a clear and concise description of how the system works.Communication: Sequence diagrams can be used as a visual aid to communicate system behavior and design to stakeholders, such as developers, project managers, and clients.Designing new systems: Sequence diagrams can be used as a tool to design new systems, by helping to identify the components needed and how they should interact.Understanding system behavior: Sequence diagrams can help you understand how different parts of a system interact with each other, and how the system behaves in response to different inputs.Here are some common use cases for sequence diagrams: Sequence diagrams are particularly useful for designing and testing software systems that involve multiple components, asynchronous events, or complex control flows. They are great for understanding how code works because they show enough detail to communicate the key elements of code behavior while being compact enough to fit a lot of information onto a single page. They show the flow of messages and the order in which these messages are exchanged. Sequence diagrams are a type of Unified Modeling Language (UML) diagram that shows the interactions between different components or objects in a system over time. Then I’ll show how AppMap makes sequence diagrams even better, by (a) generating diagrams from your running code and (b) making diagrams fully interactive. I’ll also give you a tour through the features of sequence diagrams, and explain how to use each feature to interpret the behavior of your code. In this article, I’ll introduce sequence diagrams and describe what they are good for. You may have heard about or experienced the value of sequence diagrams.
