What is the term for the visual bar chart showing project activities and their timelines?

• A. Network Diagram
• B. Resource Histogram
• C. Timeline Matrix
• D. Gantt Chart

Answer: (D)

A Gantt chart is a visual bar chart that shows project activities and their timelines. Each activity is represented by a horizontal bar positioned along a time axis; the left end marks when the activity starts and the right end shows when it finishes. The length of the bar indicates duration, and the placement along the time axis reveals when activities occur and how they overlap. This format makes it easy to plan the schedule, see sequencing and potential overlaps, and monitor progress at a glance. Other charts fill different roles. A network diagram focuses on the relationships and dependencies between tasks using boxes and arrows rather than calendar dates. A resource histogram emphasizes how resources are allocated over time rather than when tasks occur. A timeline matrix isn’t the standard tool used to depict a task-by-timeline view like a Gantt chart.
