I am currently working on a project dealing with dynamic complex
impedance matching based on frequency response data. I would like to
be able to draw representations of the source and load impedances
using the Smith Chart representation, and was wondering if anyone had
any code (preferably in C, but I'm not picky) which draws Smith
Charts, or similar transmission line type representations.

Although I am familiar with drawing Smith Charts manually, it would
seem to me that there must be some tricky ways of getting a computer
to draw the chart without going through all the hassles of drawing one by
hand. In particular, I'm interested in numerical methods to construct the
normalized reactance circles, radial reflection scales, probe ratio
overlays, and methods of drawing Reike diagrams for oscillator load
characteristics. 

Any pointers to printed references or existing code will be greatly
appreciated.
