Domain coloring allows for the visualization of complex functions with color-lookups via a pre-image. The white grid lines correspond to function values with integer real or imaginary part. All other complex numbers are mapped to different colors by their angle to the positive real axis, using four color spectra, one for each quadrant. By placing zeros and poles in a highly symmetric configuration, we deform the coordinate axes shown in black into heart shapes. The image was created digitally by a pixel-wise evaluation of the input function.
Poincaré disk model of the hyperbolic plane with a large set of somewhat clustered, light gray points. On top of this, a hierarchical structure that resembles a quad tree, but with circularly bent pieces. The hierarchy is almost everywhere sparse, except for a dense area in the east of the disk around a bold, red X-mark.
