A spiral is a plane curve, or part of a plane curve, which can be expressed in polar coordinates in the form:

$r = \map f \theta$

where $f$ is either (strictly) increasing or (strictly) decreasing.

Hence a spiral is a plane curve which emanates from a central point, getting progressively farther away (or closer in) as it revolves around that point.
