A Gantt chart is which type of scheduling tool?

A Gantt chart is classified as a bar chart scheduling tool. It visually represents a project schedule by displaying individual tasks along a horizontal timeline. Each task is depicted as a bar, where the length and position of the bar correspond to the task's duration and start and end dates. This allows project managers and team members to quickly assess the overall timeframe for the project, how different tasks overlap, and the sequence of tasks.

The clarity and simplicity of a Gantt chart make it an effective tool for tracking progress and managing time, facilitating communication among stakeholders about the project's status. The other options—activity on arrow network, activity on node network, and precedent diagram—represent different methods of illustrating project tasks and their interdependencies, typically used in more complex project management scenarios rather than the straightforward time-based representation offered by Gantt charts.
