FAQ
Frequently Asked Questions
What is a critical path diagram?
A critical path diagram maps every task in a project and identifies the longest sequence of dependent tasks that determines the earliest possible finish date. On a Gantt chart, the critical path is typically highlighted so project managers can see exactly which tasks must stay on schedule to avoid delaying the project.
How do I make a critical path diagram with a Gantt chart?
Add your tasks, set start dates and durations, then link each task to the tasks it depends on. Mark the tasks on the longest dependency chain as 'Critical.' MakeCharts renders the full Gantt chart instantly, giving you a visual critical path you can share or export.
Is this critical path diagram maker really free?
Yes. The core Gantt chart builder — including tasks, dependencies, sections, and milestones — is free with no sign-up required. You can download your chart as a PNG at no cost. Pro plans unlock CSV upload, SVG export, AI credits, and embed codes.
Can I show task dependencies on the Gantt chart?
Yes. Each task has a 'Dependencies' field where you enter the IDs of tasks that must finish before it can start. The Gantt chart renders the dependency chain so the critical path is visible at a glance.
What is the difference between a critical path diagram and a regular Gantt chart?
A standard Gantt chart shows tasks on a timeline. A critical path diagram goes further by identifying which chain of dependent tasks controls the project end date. In MakeCharts, you create both at once: build the Gantt, add dependencies, mark critical tasks, and the diagram shows your critical path automatically.
Can I use AI to generate a critical path Gantt chart?
Yes. Describe your project in plain text — phases, team size, rough timeline — and the AI will generate a complete Gantt chart with tasks, durations, dependencies, and status labels. You can then edit any detail manually. Free accounts get AI credits to try this immediately.
What task statuses can I use on the Gantt chart?
MakeCharts supports five status types: None (default), Active (in progress), Done (completed), Critical (on the critical path), and Milestone (key checkpoint). Each status renders with a distinct visual style so stakeholders can read the chart at a glance.
Can I export the critical path diagram as an image?
Yes. Download your Gantt chart as a PNG for use in slides, reports, or documents. SVG export (vector, infinitely scalable) is available on paid plans. Both formats are presentation-ready with no further editing required.
How do I handle weekends or non-working days in the timeline?
The 'Exclude Days' setting lets you specify which days to exclude — for example, 'weekends' — so your Gantt timeline skips non-working periods and your duration calculations stay accurate.
Can I embed the critical path diagram on my website?
Yes, on Plus and Pro plans you get an embed code that lets you display a live, responsive Gantt chart on any webpage, internal wiki, or Notion document — no screenshot needed.
