To use the function, you provide the current value and its original range, followed by the target range you want it to move into. : The incoming number to be remapped.

: Converting complex datasets, such as temperature readings or geographic coordinates, into visual properties like circle diameters or pixel positions on a canvas.

: let diameter = map(mouseY, 0, height, 20, 300); — This ensures that as the mouse moves vertically, the size of an object scales proportionally within a specific range.

The map() function in p5.js is a cornerstone of creative coding, used to translate a value from one numerical range to another. Whether you are using mouse movements to control colors or scaling data sensor values to fit a canvas, map() simplifies the math required to keep elements in proportion. The Core Syntax To use the function, you provide the current

: Using map() inside loops to translate counter variables into varying shapes, sizes, or spacing to create structured generative art.

: You can reverse values by swapping the target bounds (e.g., mapping 0–100 to 255–0 ), causing an element to decrease in size or intensity as an input increases. Practical Examples For more technical details, you can visit the official p5

: The lower and upper bounds of the target range.
