hobby – An im­ple­men­ta­tion of Hobby’s al­go­rithm for PGF/TikZ

This pack­age de­fines a path gen­er­a­tion func­tion for PGF/TikZ which im­ple­ments Hobby’s al­go­rithm for a path built out of Bezier curves which passes through a given set of points. The path thus gen­er­ated may by used as a TikZ ‘to path’.
The im­ple­men­ta­tion is in LaTeX3.
