The shortest splitline algorithm (formal statement) for districting was implemented as a computer program by Ivan Ryan.
The program inputs standard US government Census Bureau files describing the shape of each state and the population distribution inside it.
It outputs a multicolored picture (.bmp file) depicting the state, its splitline-method districting (different colors for different districts), and the population density inside the state (brightness-level map).
