Python-powered interactive mathematics

Distribution Playground

Explore probability distributions directly in your browser. HTML controls drive the same Python state and Matplotlib plotting code as the desktop tools, running locally through WebAssembly.

ln

LogNormal

Compare time and log-time parameterizations with synchronized controls.

Open visualizer → n,p

Binomial

Explore success-count probability masses and the cumulative distribution.

Open visualizer → r,p

Negative Binomial

Study failures before a fixed number of Bernoulli successes.

Open visualizer → μ,φ,p
