A project team wants to graphically illustrate the logic of a subprogram. Which of the following would be the BEST choice?

Image editing software is primarily designed for manipulating raster or vector images, not for creating structured logic diagrams efficiently.

Word processing software is designed for text-based document creation and lacks the specialized tools and efficiency needed for complex logic diagrams.

Presentation software is for creating slide-based presentations and, while it can embed diagrams, it is not the most efficient or specialized tool for generating detailed logic illustrations from scratch.

Visual diagramming software is purpose-built for creating detailed graphical representations like flowcharts, UML diagrams, or data flow diagrams, which are ideal for clearly illustrating the sequential steps and decision logic within a subprogram.
