Educational Research Design Module (Week 3)
The following is the research work I carried out on the week immediately after the class that took place on 2nd May 2017. I was interested in finding out if I could install the free Graphviz software on my Apple Mac computer.
Graphviz
Graphviz is open source graph visualization software. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.

I was interested in finding out if Graphviz could be used as a domain model authoring tool in my MSc Applied Project. The following is a set of notes that describe my attempts to install this software. It is important to have these notes so that one does repeat the same failed installation processes in the future.
