PiChart turns the digits of π into a beautiful animated circular chart, helping you explore mathematics through pattern, motion, and visual curiosity. Place the digits 0–9 around a circle, then follow the digits of π one by one. For every pair of consecutive digits, PiChart draws a line from one number to the next. As more digits are added, a colourful woven pattern begins to appear. Whether you are a student, teacher, maths enthusiast, or simply someone who enjoys visual patterns, PiChart offers a calm and interactive way to explore one of the most famous constants in mathematics. Main features: • Visualise the digits of π as circular chord patterns • Animate the drawing process with Play and Pause • Step through digits manually for closer observation • Adjust playback speed from slow to fast • Choose how many lines / digits to display • Show or hide number ticks around the circle • Copy the currently displayed digits • Simple, elegant dark interface designed for focus • Works fully on-device with no account required PiChart is designed as an educational and creative maths visualisation tool. It does not require sign-in, does not use location, and does not collect personal data.
