Gabor Doka, developer of SankeyHelper is currently working on SankeyTurtle, the implementation of a simple language for arrow routing in his Excel macro-based diagramming tool SankeyHelper. SankeyTurtle is currently being beta-tested.
The idea of SankeyTurtle code is to give each Sankey flux – each data cell – an accompagnying instruction how to draw the flux exactly in terms of path and geometry. The SankeyTurtle syntax is based on the vintage Logo TurtleGraphics drawing language, where you tell an imaginary turtle with a pen attached to it’s tail commands like “Move Forward” and “Turn Right 90°” and record the trail of the pen.
This will definitely an exciting improvement for all users of the SankeyHelper freeware … sorry, Sankeyware.
I’ll keep you posted about the progress and any official release.
