FAQ
Frequently Asked Questions
What is a tree diagram maker?
A tree diagram maker is an online tool that lets you visually map hierarchical structures — like org charts, reporting lines, or category trees. MakeCharts makes it easy to build, customize, and export tree diagrams without any design or coding skills.
Is this tree diagram maker really free?
Yes. You can create, customize, and download tree diagrams for free with no sign-up required. Free accounts also include limited AI credits to try AI-powered generation. Paid plans unlock more AI charts, file uploads, and embed codes.
Can I make an org chart with this tool?
Absolutely. The organizational chart builder is purpose-built for org charts. You can define position titles, team member names, and departments, then arrange them in a clear hierarchy. It supports collapsible departments and adjustable layouts for large teams.
How do I create a tree diagram with AI?
Type a description of your hierarchy into the prompt box — for example, 'CEO with three VPs: Engineering, Marketing, and Operations, each with two direct reports.' The AI will generate a tree diagram instantly. You can then edit any node to refine it.
What is the difference between a tree diagram and an org chart?
An org chart is a specific type of tree diagram used to show organizational hierarchy — who reports to whom. Tree diagrams are a broader category that can represent any branching structure, from file systems to decision trees. MakeCharts supports both use cases in the same tool.
Can I export my tree diagram as a PNG or SVG?
Yes. Once your tree diagram is ready, download it as a high-resolution PNG for use in presentations and documents, or as an SVG for scalable, print-ready output. Both formats are supported on free and paid plans.
How many levels deep can my tree diagram go?
There is no hard limit on depth. You can nest positions as many levels as your structure requires. For very large hierarchies, the department collapse feature helps keep the view manageable and focused.
Can I share my org chart with my team?
Yes. Generate a shareable link to send your tree diagram to anyone — no account needed to view. On Plus and Pro plans, you can also embed the chart directly on your intranet or website using an embed code.
Does the tree diagram maker work on mobile?
Yes. MakeCharts is fully responsive and works on phones, tablets, and desktops. You can create, edit, and share tree diagrams from any device without installing an app.
Can I upload a spreadsheet to build my tree diagram?
Yes, on Pro and Max plans you can upload CSV or Excel files containing your organizational data to generate a tree diagram automatically. On free plans, you can paste data from a spreadsheet directly into the node editor.
