Generate some chord sequences to start the creative process

Inspired by a graph I found in the book "Making music, 74 strategies for electronic music producers", this is a small script that will generate graphs with plausible chord sequence based on the abstract schema:

• The .dot files represents the graphs
• The .pdf files are printable representations of the graphs.
• The .sh file generates both the .dot and .pdf files.
• The .key file is a keynote file that contains some of the graphs in a compact form on a single page.
