# Kafka Concepts Visualizer

An interactive web-based visualization tool to help developers understand Apache Kafka's core concepts: topics, partitions, consumer groups, and message flow patterns.

🔗 [Live Demo](https://idsulik.github.io/kafka-concepts-visualizer/)

![Kafka Visualizer Preview](https://github.com/user-attachments/assets/d9c06a26-8e10-4d2d-9c04-1837ed9b77b5)

## Features

- 🎯 Interactive visualization of Kafka's core components
- 🔄 Real-time message flow animations
- 👥 Dynamic consumer group scaling demonstration
- 📊 Visual partition distribution
- 🎨 Clean, modern UI design

## About

This visualizer was created to help developers better understand Kafka's core concepts through interactive visualization. It's particularly useful for:

- New developers learning Kafka
- Teams explaining Kafka architecture
- Educational purposes in workshops and training
- Quick demonstrations of Kafka concepts

## Getting Started

1. Clone the repository:
```bash
git clone https://github.com/yourusername/kafka-visualizer.git
```

2. Open `index.html` in your web browser or serve it using a local server:
```bash
# Using Python
python -m http.server 8000

# Using Node.js
npx serve
```

3. Visit `http://localhost:8000` in your browser

## Future Improvements

- [ ] Add more complex scenarios (multiple consumer groups)
- [ ] Implement message key visualization
- [ ] Add replication factor visualization
- [ ] Include broker failure scenarios
- [ ] Add interactive tutorials
- [ ] Implement mobile-responsive design
