Research has shown that we can distinguish between hard science and soft science disciplines based on the level of graph use, so it can be argued that there is a correlation between scientificity and visuality[1][2]. Furthermore, natural sciences appear to make heavier use of graphs than social sciences and mathematics[3].
Papers on this area have been published by academics of University of Maine.
It has been claimed that an example of a discipline that uses graphs heavily but is not at all scientific is technical analysis.[4]
