        cplot is an attempt at encoding complex-valued data in colors. The general idea is to
        map the absolute value to lightness and the complex argument (the "angle") to the chroma
        of the representing color.
        
        The representation is chosen such that
          * values around 0 are black,
          * values around infinity are white,
          * values around +1 are green,
          * values around -1 are red,
          * values around +i are blue, and
          * values around -i are yellow.
        
        See below for examples with some well-known functions.
        
        
        ```python
        import cplot
        import numpy
        
        cplot.show(numpy.tan, -5, +5, -5, +5, 100, 100)
        
        # There is a tripcolor function as well for triangulated 2D domains
        # cplot.tripcolor(triang, z)
        ```

        ### Testing
        
        To run the cplot unit tests, check out this repository and type
        ```
        pytest
        ```
        
        ### Distribution
        
        To create a new release
        
        1. bump the `__version__` number,
        
        2. tag and upload to PyPi:
            ```
            make publish
            ```
