Watch Sorting Algorithms in Action: Build a Python Visualizer in Minutes

3 min readFeb 13, 2025

Ever wondered how your computer sorts data so fast? Imagine watching the magic unfold in real time! In this tutorial, you’ll learn how to create a visualizer for sorting algorithms using Python. We’ll use a simple Bubble Sort algorithm to demonstrate, and by the end, you’ll have a neat animation that brings abstract code to life.

Why Visualize Sorting?

Sorting algorithms are the backbone of many programming challenges. But while theory is essential, nothing beats seeing the process in action. Visualizing the sorting process not only reinforces the concepts but also makes learning a lot more fun!

Prerequisites

Before we dive in, make sure you have:

  • Python 3.x installed on your machine.
  • The following Python libraries:
    - matplotlib
    - numpy
    (optional, for generating random data)

You can install the required libraries with:

pip install matplotlib numpy

Step 1: Setting Up the Project

Create a new Python file called visual_sort.py. We’ll start by generating a random list of numbers to sort:

import random

def generate_data(n=50…
