Which chart offers a visual breakdown of a project’s completion status?

A Gantt chart provides a visual representation of a project's schedule, showing the start and end dates of specific tasks, along with their duration. It allows project managers and teams to see at a glance which tasks are in progress, which are completed, and which are yet to start. Each task is represented as a horizontal bar, with the length of the bar indicating how long the task is expected to take. This format makes it easy to assess the overall status of the project, track progress, and identify any delays.

Other types of charts mentioned do not serve the same purpose. A pie chart is typically used to represent proportions of a whole, such as budget allocation or market share, and does not provide information about the timeline or status of project tasks. A bar graph is useful for comparing quantities across different categories but doesn't convey task completion status over time. A flowchart depicts processes and workflows but does not represent progress or project timelines directly. Thus, a Gantt chart is uniquely suited for tracking completion status in project management contexts.
