Visualization is an important research tool that puts data into a spatial context to effectively communicate information and create a visceral, emotional connection to the results. Visualization has been used to help understand data, processes, structures, and concepts in fields ranging from engineering to humanities and from health sciences to social sciences. The most widespread forms of visualization are graphs, pie charts, work flows, illustrations, photographs and animations.
Well-designed visualizations are powerful communication tools that support recall, inference, and decision-making. In one of the most famous works of graphic visualization, Napoleon’s March, Charles Minard, a French civil engineer, visually described the losses suffered by Napoleon’s army in the Russian campaign of 1812.
