Enter a price and diameter for at least two pizzas.
Every pizza in the running gets its place. The best deal turns green, the runner-up yellow once three or more are in. Pies are drawn to scale against the largest diameter entered. The price is the total for that many pizzas (2 for $20).
Better deal = lower price per square inch. Area grows with the square of the diameter, so a 16" has 1.78× the pizza of a 12", not 1.33×.
Cheaper by X% is measured against the runner-up's price per square inch; vs best against the winner's. Same gap, opposite ends.
