In the just-concluded series "This article explains the data thoroughly", the author expounded the huge data system from various perspectives such as data source, collection, and cleaning. After the series of articles, many friends working in the workplace are very interested in the "top-level" data visualization related content of data application, and want to know how to conduct data visualization practice in the workplace and industry. Then, the author will start from scratch. Take you to get started with data visualization design! Because there is a lot of content, I still use a series of articles to explain it in several issues. 1. What is data visualization? Here, the understanding and definition of Stuart K.
Card, the proposer of the concept of information mobile number list visualization, is cited. He believes that understanding visualization first requires distinguishing the following two concepts. Perception is the organization, identification and interpretation of sensory information to help people understand their surroundings Cognition is a set of mental processes that include paying attention, remembering, generating and understanding language, solving problems, and making decisions Through the above concepts, it is not difficult to see that perception is more about explaining and helping people understand the surrounding environment, and it stays at the level of cognition.
While cognition includes not only inherent perception, but also solutions and actions to make decisions. It not only promotes awareness, but also acts based on awareness! Through the above conceptual analysis, it is not difficult to find that data visualization is based on cognition. And Stuart based on this point of view, put forward the definition of data visualization, that is, Visualization is really about external cognition, that is, how resources outside the mind can be used to boost the cognitive capabilities of the mind. Visualization It is a process that helps people to recognize external information, that is, a process that uses visual resources and signals outside the brain to help enhance the cognitive ability of the brain.
