A visualization of classification and regression trees.

Inputs

Tree: decision tree

Outputs

Selected Data: instances selected from the tree node

Data: data with an additional column showing whether a point is selected

This is a versatile widget with 2-D visualization of classification and regression trees. The user can select a node, instructing the widget to output the data associated with the node, thus enabling explorative data analysis.

../../_images/TreeViewer-stamped.png

Information on the input.

Display options:

Zoom in and zoom out

Select the tree width. The nodes display information bubbles when hovering over them.

Select the depth of your tree.

Select edge width. The edges between the nodes in the tree graph are drawn based on the selected edge width.

All the edges will be of equal width if Fixed is chosen.

When Relative to root is selected, the width of the edge will correspond to the proportion of instances in the corresponding node with respect to all the instances in the training data. Under this selection, the edge will get thinner and thinner when traversing toward the bottom of the tree.

Relative to parent makes the edge width correspond to the proportion of instances in the nodes with respect to the instances in their parent node.

Define the target class, which you can change based on classes in the data.

Press Save image to save the created tree graph to your computer as a .svg or .png file.
