## Explanation

This example is similar to the cubic polynomial example, and
the quintic polynomial example, except:

- The canvas is larger than in either of the polynomial examples.
- The pixels per complex unit is
*less*, so more of the complex plane is shown.
- The exponential function does not have any zeroes, so there isn't any position where the 3D
graph winds around the white circle. (Note that in the positive real part of the plane,
the exponential function outstrips the ability of the "graph scale" slider to reduce the
graph scale enough to prevent the radial component of the graph position becoming too negative.)
