How to Draw a Heart in Polar Coordinates

Everyone's aware that one can draw a "cardioid" in the polar coordinate system with the equation \(r = 1 - \cos t\). But we can do better for a heart shape, right?

A friend of a friend forwarded the following heart shape equation to me: \[r = \frac{\sin t \sqrt{|\cos t|}}{\sin t + \frac75} - 2\sin t + 2\]
