🧠 How It Works (For the Curious)
Under the hood, we use the least-squares circle fitting algorithm — a mathematical method that finds the circle minimizing the total distance from all your drawn points.
This means:
- More points = more accurate
- Jagged lines? No problem
- Even spiral doodles get “rounded up” to the nearest circle 😄
