Explained Visually

What Explained Visually actually is

Victor Powell's short pages each take a single idea from maths or statistics, such as eigenvectors, conditional probability, Markov chains or principal component analysis, and hand you a diagram to pull about. Change any input and every downstream number and shape updates immediately.

Why it is worth your time

The eigenvector page makes the definition obvious after about ten seconds of dragging, having been a memorised formula for years beforehand.
