Automated Decision Trees
SmartDraw's Decision Tree Extension allows you to generate a decision tree diagram using data.
Before you can generate a decision tree, you'll want to format your data in a format that SmartDraw can interpret.
SmartDraw will be able to understand CSV, XLS, or XLSX files.
Format your data so it contains the following columns in order: "ID", "Label", "ParentID". The ID is the unique number given to each decision you want to appear in your diagram. The label will be the name that appears inside a decision box. The "ParentID" tells SmartDraw what decisions are the children of other decisions.
In the simplest terms if you wanted to diagram a decision tree of "Should I go running" with two possible outcomes "Yes" and "No", you would give the question ID 0, "yes" ID 1, and "no" ID 2. In the spreadsheet, you'll want to mark the parent of both yes and no as "0" to indicate that they're the children of the parent question.
