Specification and Description Language (SDL) • Ditaa diagram • Gantt diagram • MindMap diagram • Work Breakdown Structure diagram • Mathematic with AsciiMath or JLaTeXMath notation • Entity Relationship diagram any. This is very handy with Word to print long diagram on several pages. (Note: this really does work. Only the first page is shown below, but it is a display artifact.) @startuml Alice -> Bob : message objects and their relationships at a specific moment in time. It provides a snapshot of the system’s structure, capturing the static view of the instances present and their associations. PlantUML offers a simple
