thinkgraph: Theory of Constraints Thinking Processes Graphing Tool

This a tool that has a mini-language to help with creating diagrams ala Theory
of Constraints Thinking Processes.

Usage

git clone https://github.com/ryanfreckleton/thinkgraph
cd thinkgraph
pip install .

Here's a basic use of thinkgraph to create an "evaporating cloud" diagram.

# hello.tkg
1. Try new things
2. Don't try new things
3. We must be satisfied
4. We must be secure
5. Happiness

1 <> 2
1 -> 3
2 -> 4
3 -> 5
4 -> 5

thinkgraph uses a very simple language.
It is divided up into entities and relations.
An entity is any line of the form:

<identifier>. <label>

Once you've created this file, running thinkgraph on it should generate a nice dot file.

 thinkgraph hello.tkg

Identifiers can be numbers, words, or letters.
Labels are ASCII sentences and continue until the end of the line.

Relations are how relationships between entities are graphed. The relationships are:

<>  conflict
->  cause
=>  feedback loop

Styling of entities is determined by a code after the period.

1.i An action
2.o An obstacle
3.g Something green
4.r Something red
5.y Something yellow
