Data Structures and Algorithms Visualization

Sort Visualizer animates classic sorting algorithms, including insertion sort, merge sort, quick sort, and heap sort, so you can watch how each one orders data. Built by Ramiz Rahman entirely in React with no third-party JavaScript or CSS libraries, it suits students and developers studying algorithm behaviour.

An interactive playground for visualizing classic search algorithms, including breadth-first, depth-first, iterative deepening, greedy, uniform cost, A*, and IDA*. Computer science students and developers can watch each strategy explore a search space step by step, making it a practical study aid for algorithms coursework and interview preparation.

An online quiz application built with React and delivered as an installable progressive web app. It lets users take quizzes directly in the browser without installing a native app. Suited to learners who want quick knowledge checks and to developers exploring a simple React-based PWA implementation.

An installable, in-browser audio spectrum analyzer that visualizes frequencies in real time. It can analyze live input from your microphone as well as audio files. Suited to musicians, audio engineers, and hobbyists who want a quick frequency visualization without installing desktop software.

Visualize JSON data as an interactive graph. Paste any JSON and instantly see the structure as nodes and edges. Essential for understanding complex nested API responses.

Calculate in a notebook and share — from everyday math to engineering. Use variables, functions, and units and see results immediately. Add comments, copy calculations to apps like Word or Excel, or share them through an editable link. Calculate thermodynamic fluid properties with the integrated CoolProp library.
