Estimate π using randomness

Sample random points in a square. Count how many land inside a quarter circle. Four times the fraction inside estimates π.

What you get

• A reproducible estimate, error measurement, and statistical interval.
• A plot of sampled points and a convergence graph.
• CSV data to download and a public JSON API.
