I find Information Visualization extremely interesting, and it was through a PhD-level course I took during my Master's studies that I came to realize how many terrible plots any scientific journal/article contains on a regular basis. I can clearly see that there is a potential for a vast number of Information Visualization jobs/tasks out there, but how about the actuality of it? Is there in reality any market/demand for that? Is it possible to easily get a job as an Information Visualizer?
I have been even considering doing thesis related to InfoVis, but I am not sure how appreciated that would be later on when finding a job? Won't my degree be overlooked when they see that my thesis was not done in a more strictly Bioinformatics-related topic but was instead done about InfoVis in Bioinformatics?
