Visu

Visu bridges the gap between pseudocode and the mental model of how

algorithms and data structures behave. Write pseudocode in the editor,

press Run, and watch arrays, stacks, queues, deques, linked lists, sets,

maps, and directed or undirected graphs animate step by step.

Features:

Simple pseudocode language with eight built-in structures: array, stack, queue, deque, linked list, set, map, and graph

Step-by-step timeline with play, pause, step, and scrub controls

Minimalist split layout with the canvas on the left and editor on the right

Built-in pseudocode reference and example programs (bubble sort, DFS, union-find, and more)
