An Activity Diagram resembles which type of chart?

An Activity Diagram is a visual representation used in systems analysis and design to depict workflows and processes. It resembles a horizontal flow chart because it illustrates the sequence of activities and the flow of control or data from one activity to another in a left-to-right orientation.

In an Activity Diagram, activities are represented by rounded rectangles, and the transitions between these activities are indicated by arrows, showcasing how one activity leads to another. This structure effectively communicates the progression of tasks and decision points in a process, which is characteristic of flow charts.

While a vertical flow chart would typically display processes in a top-down manner, the horizontal format aligns more closely with the nature of Activity Diagrams, allowing for a more extensive layout that can accommodate complex workflows. The other chart types mentioned, like bar charts and line charts, do not serve the same purpose as they focus on representing data visually rather than illustrating the flow of activities in a process.
