Draw Linked Lists and Trees

Paste a linked list or a tree below to visualize it. Paste more than one to draw them all.

from drawing import drawing_tool
drawing_tool()

For a linked list, each Link is a pair of boxes containing its first (left box) and rest (right box) attributes. A slash in the rest box is an empty linked list. An item that is itself a linked list points down to a row of its own.

A tree is drawn with each label above its branches and an arrow from the label to the root of each branch.

This page doesn’t evaluate Python code. It just visualizes linked lists and trees. Values contained within them are shown as written.
