Entropy Visualizer & Simulator – Interactive Entropy Heatmap for Randomness Testing

The Entropy Visualizer & Simulator is an advanced entropy modeling playground built entirely with HTML, CSS, and JavaScript. This tool allows cybersecurity professionals, IT admins, and students to interactively simulate and visualize entropy generation from various simulated and real input sources like noise, mouse movements, and keystrokes. 🔐

It features a heatmap-style entropy grid, real-time dynamic entropy graph, and keyboard/mouse input detectors—all running client-side with responsive layouts, a polished dark-mode UI, and entropy source switching.

Loaded with LocalStorage for state-saving and packed in a neat design, use this simulator for educational demonstrations, security entropy quality checks, or simply to visualize cryptographic randomness like never before.
