Enter a price and diameter for at least two pizzas.
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. Qty multiplies the area, so enter the total price for that many pizzas.
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.
