Research into the potential of deploying an adjacency list in postgresql to implement a comprehensive graph model
This is some sample code that is to be kept for future reference. The .py file is to be run. It generates the out.dot file (to be used with a program like graphviz) as well as generates a csv that can be inserted into the table for use. The .sql file contains the setup to make the table, some demo insertion queries and all of the work that allows the queries to work on the table task Each .sql function has a explanation comment before it as well as some demo code after it with a comment that explains some use cases for that function.
