Produce a definition of data visualization. Explain how it caters to the perceptual abilities of humans.
What will be an ideal response?
The idea of data-driven pictures is called visualization and is
defined as the graphical representation of data to amplify cognition (Card,
2012; Ware, 2013). The abstract characteristic of the data is what distinguishes data visualization from scientific visualization. For scientific visualization, three dimensions are necessary, because typical questions involve continuous variables, volumes, and surfaces (inside/outside, left/right, above/below). However, for data visualization, typical questions involve more categorical variables and the discovery of patterns, trends, clusters, outliers, and gaps in data, such as stock prices, patient records, or social relationships.
