What is algviz?

Algviz is an algorithm animation engine for your Python code in Jupyter, which supports multiple data structures such as vector, table, linked_list, tree and graph.

Vector	Table	Tree	Graph

You can get live algorithm animation after bringing some algviz interfaces to your algorithm. For example, this code below shows the bubble sort algorithm:

Click to show the code example

import algviz

def bubble_sort(data):
    viz = algviz.Visualizer(0.5)
    vector = viz.createVector(data, cell_size=(40, 160), histogram=True)
    for i in range(len(vector)):
        for j in range(len(vector)-i-1):
            if vector[j] > vector[j+1]:
                vector.mark(algviz.cRed, j)
                vector.mark(algviz.cGreen, j+1)
                viz.display()
                vector.swap(j, j+1)
            else:
                vector.mark(algviz.cRed, j+1)
                vector.mark(algviz.cGreen, j)
            viz.display()
        vector.mark(algviz.cGray, len(vector)-i-1, hold=True)
    vector.removeMark(algviz.cGray)
    viz.display()

bubble_sort([5, 4, -2, 1, -1, 3])

The rendered animation looks like this:
