How to Make a Tree Diagram
From blank canvas to polished org chart in three simple steps.
Define Your Root Node
Start with the top of your hierarchy — typically the CEO, department head, or project lead. This becomes the trunk of your tree diagram.
e.g. 'CEO - Sarah Chen' as your root position
Add Branches and Positions
Click '+ Child' to add reporting positions beneath any node. Fill in job titles, names, and departments to build out the full organizational structure.
e.g. VP Engineering, VP Marketing, VP Operations reporting to the CEO
Customize and Export
Adjust spacing, font size, and connection styles. Toggle labels, enable department collapse, and export your finished tree diagram as PNG or SVG.
e.g. download a high-res PNG for your next all-hands deck

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.
