Which graphical tool is commonly included in progress reports to display an overview of project status?

The Gantt chart is commonly included in progress reports because it effectively provides a visual overview of a project's status over time. It illustrates the start and end dates of various project tasks, along with the progress made on each task. This allows stakeholders to quickly understand which tasks are on schedule, which are delayed, and the overall health of the project timeline.

Gantt charts also facilitate project management by visually mapping out dependencies between tasks, making it easier to identify which activities may affect others. This tool is particularly useful in project tracking, as it provides a comprehensive snapshot of workload distribution and the remaining steps to project completion.

Other graphical tools like bar graphs, pie charts, and flowcharts serve different purposes. Bar graphs are generally used for comparing quantities across different categories; pie charts represent parts of a whole, providing a clear breakdown of percentage distributions; and flowcharts illustrate processes or workflows. While these tools are valuable in their own contexts, they do not provide the detailed time-based tracking that a Gantt chart offers, making the latter the most suitable choice for progress reporting in project management.
