How Data visualization works – brain–

– Visual attributes like color, size, shape, relative proximity, and other on-screen elements are critical to the human comprehension of data visualizations. Human factors are, in fact, the most important things to be taken into consideration when designing a visualization system. Tapping the huge knowledge base about human visual sensation and perception developed over the years by the scientific community is enabling data visualization software developers to create systems that enable extremely fast understanding of even the largest and most complex hierarchical data sets as well as data sets that are constantly changing.

– That’s why designing new visualization systems geared for the human visual system is so important. Our eyes have enormous potential for perception; the bandwidth of human vision is huge compared to our other senses. We can very quickly scan, recognize and recall images, and can easily detect changes in size, color, location, movement or texture.
