What is a tree diagram?

A tree diagram (or decision tree diagram) is a map of possible outcomes in a series of related choices. It’s a tool for weighing decisions about future actions based on cost, probability, and benefit. The two main types of tree diagrams include classification trees and regression trees. Use a classification tree to evaluate yes or no answers and a regression tree to predict numeric values based on data.

How to make a tree diagram

Open our tree diagram generator

Start from a blank canvas or customizable template. Use a blank canvas when you want manual control over building your tree diagram. Use a template when you need help getting started or want a polished layout.

Define and add the root node

Consider the following question: What is the starting point or main idea for your decision-making process? The root node is the topmost symbol in any tree diagram and has no incoming branches.

Add child nodes

Break down the root node into a series of concepts or hierarchical steps. Child nodes can include decision nodes, where a decision has to be made, and chance nodes, where there are multiple uncertain outcomes.

Label the nodes

Add clear labels to make the decision tree easy to understand and follow. You can customize text options in Lucidchart, including font, size, and color.

Connect nodes with lines

Add lines to connect the root node to child nodes and additional branches. At the end of each set of branching nodes is an end node indicating a final outcome.

Keep it organized

Use standard decision tree symbols and notations throughout your diagram. Use consistent colors, shape sizes, text formatting, and spacing.
