A Gantt chart is a project management tool that visually displays tasks, their durations, and timing along a horizontal timeline. Each task appears as a horizontal bar spanning from start to end date, making it easy to see what should happen when, which tasks overlap, and how the project progresses over time. Named after Henry Gantt who popularized the format in the 1910s, Gantt charts help plan, coordinate, and track projects. Modern software generates Gantt charts that show task dependencies (which tasks must finish before others can start), critical path (the sequence determining project duration), resource assignments, and progress tracking. Municipal infrastructure projects, budget development processes, and major initiatives commonly use Gantt charts for planning and communication. While powerful for scheduling, Gantt charts can become unwieldy for very large or complex projects with thousands of tasks.
