CS Visualizer

Visualize your Java and C# code directly inside VS Code — without leaving your editor.

This extension is a companion to the CS Visualizer desktop app. It connects to the app running locally on your machine and renders visualizations inside a VS Code panel. The desktop app must be installed and running.

Right-click any code selection to open:

• Flowchart — visualize control flow
• Recursion Tree — trace recursive calls step by step
• Complexity Analyzer — Big-O analysis of your algorithm
• OOP Diagram — class hierarchy and runtime visualization
• Data Structures — animate arrays, linked lists, trees, stacks and more

Getting Started

1. Download and install the CS Visualizer desktop app from cs-visualizer.com
2. Launch the app — it runs a local server on port 8080
3. Open any Java or C# file in VS Code, select some code, right-click and choose a visualizer

Requirements

The CS Visualizer desktop app must be running before using this extension. If it's not running, the extension will prompt you to download it.
