(Note: I will e-mail pics to professor as they will not download here.)
3) The Fruchterman Rheingold program changes the scheme into an almost hexagon like shape. In this simulation, the inner words are prose and irony, and they are surrounded by all the other words that intersect in this formation in the photograph. It leads to another kind of meaning, because of the nuance when these words are mentioned, also bring eventually these other words into the limelight. This is another layer to explore and quite helpful.
4) I can see the advantages of working small and medium sized visualizations. Smaller ones would be useful in the case of zeroing in on certain aspects of research, narrowing the focus of a single subject or word, for instance. Medium sized visualizations would work better for larger groups of words or showing how graphs can change over measurements of time. Measuring the data of literature is not a business set in stone, though. I suggest incorporating these tools, but to not wholly rely on them to get all the answers. Updating models will be paramount as technology keeps changing and better tools are developed. Even more importantly, close readings still need to be maintained for what machines miss that only humans can see.
