Final answer:
A flowchart is the tool used in program design for a graphic presentation of the detailed steps needed to solve a programming problem. It uses symbols like rectangles and diamonds connected by arrows to map out processes. Unlike Gantt charts, Venn diagrams, and scatter plots, flowcharts are specifically designed for illustrating program logic.
Step-by-step explanation:
In the context of program design, a flowchart is the tool that presents a graphical representation of the detailed sequence of steps needed to solve a programming problem. A flowchart utilizes various symbols to represent different types of actions or steps in a process. For example, rectangles are used for process steps, diamonds for decisions, and arrows show the flow from step to step. This is highly effective in both planning a program and explaining the logic to others. It is far easier to understand a complex process when you see a visual representation laid out in a flowchart compared to written descriptions or code.
Other tools like Gantt charts, Venn diagrams, and scatter plots also visualize information but serve different purposes. Gantt charts are used for project management to show the timeline of tasks, Venn diagrams for showing logical relationships between different sets, and scatter plots for representing data points on a horizontal and a vertical axis to show how much one variable is affected by another.
