Decision Trees, By the Numbers
How to Create a Decision Tree
From blank canvas to finished diagram in four simple steps.
Set Your Root Decision
Start with the core question or decision you need to map. Label the root node clearly so every branch flows from a single, unambiguous starting point.
Root node: 'Launch New Product?'
Add Branches and Node Types
Add child nodes for each possible choice or event. Assign each node as a Decision, Chance, or Outcome node to reflect the nature of that step.
Branches: 'Invest in R&D' (Decision) vs. 'No Investment' (Decision)
Label Edges with Conditions
Add conditions or probabilities to each connecting edge so stakeholders understand what triggers each branch.
Edge: 'High Demand (0.7)' leading to 'Market Success'
Export and Share
Download your decision tree as PNG or SVG, or copy a shareable link. Drop it into a presentation or embed it on your site.
Export as PNG for a board presentation or share a link with your team

Frequently Asked Questions
What is a decision tree creator?
A decision tree creator is an online tool that lets you build visual diagrams mapping decisions, chance events, and outcomes as a branching tree structure. MakeCharts provides an interactive editor with Decision, Chance, and Outcome node types, edge condition labels, and probability inputs — plus an AI generator that builds an initial tree from a plain-language description.
Is this decision tree creator free?
Yes. You can create, customize, and download decision trees for free without signing up. Free accounts also include a limited number of AI credits to generate trees from natural language. Paid plans unlock more AI credits, SVG exports, and embed codes.
How do I make a decision tree online with AI?
Type your decision scenario into the input box and click 'Create Your Decision Tree.' The AI reads your description, identifies key decision points, chance events, and outcomes, and builds an initial tree you can then edit. You can add or remove nodes, change types, and update edge conditions directly in the editor.
What types of nodes does the decision tree tool support?
MakeCharts supports three node types: Decision nodes (for choices you control), Chance nodes (for probabilistic events), and Outcome nodes (for end results). Each type has a distinct color you can customize, making it easy for readers to follow the logic at a glance.
Can I add probabilities to my decision tree?
Yes. Each edge (the line connecting two nodes) supports a probability value between 0 and 1, plus a text label for the condition or event name. You can toggle probability display on or off in the Display settings panel.
