Tree Diagram Examples

Seven ready-made trees across every mode. Each one opens in the editor exactly as shown — change a line, and it's yours.

Company org chart

Tree diagram

Open in editor

A three-level hierarchy — the everyday tree diagram. Type a name per line, indent to nest.

Launch decision tree

Decision tree

Open in editor

Square-one decision analysis: branch labels in [brackets] become edge labels, leaves are outcomes.

Two coin flips (probability)

Probability tree

Open in editor

Probabilities in (parentheses) sit on each branch and multiply along every path — each leaf shows P = 0.25.

Marbles without replacement

Probability tree

Open in editor

3 red and 2 blue marbles, drawing twice without replacement. Fractions like (3/5) work too.

Simple family tree

Tree diagram

Open in editor

Three generations, oldest at the top. For clinical genograms with standard symbols, use a genogram tool.

Syntax tree (linguistics)

Tree diagram

Open in editor

“The cat sat on the mat” parsed as a constituency tree with the bare Linguist theme.

Project file tree (text output)

Text tree

Text mode turns any outline into a copy-paste ASCII tree for READMEs, docs, and code comments.

Using these examples

Every example is plain text under the hood — the same indented outline you'd type yourself. Open in editor loads it into the tree diagram maker via the share link, so nothing is installed or saved until you start editing. From there you can switch modes (the marble tree makes a fine plain hierarchy; the org chart becomes a text tree), restyle with themes, and export as PNG, PDF, or copyable ASCII. For mode-specific guidance, see the decision tree, probability tree, and text-to-tree pages.
