Decision Tree View

The view can be accessed either via the “Open view” action on the executed node or on KNIME Hub. A plot of the provided decision tree using a JavaScript based library. The view shows a decision tree consisting of a number of nodes. The class label and the class counts displayed inside the nodes correspond to those of the training data. Additionally a static SVG image can be rendered, which is then made available at the first output port.
