The Concept Study Of Data Visualization Under The Ackground Of Big Data

Data, which is well known as a recording mark, has a very long history. Today, it is no longer confined to the chart in the number, symbol or form; it is no longer stored in a computer analysis of the resources, waiting for people to select. With the recent rapid development of smart phones and wearable smart devices, every subtle change, including the rise of people’s daily life sentence, an action, location, etc. and even physiological data can be recorded and analyzed."Big data" has long been the rise and become one of the most popular words.Not only unlimited possibilities but also enormous challenges come to people with the data time. Today, the understanding of data visualization is not uniform according to individuals. There is no standard so people engaged in visual working have their own understanding while people engaged in related industries. Evidently, data visualization is not comprehensive from only one angle and we cannot achieve unity with each other about the problems of concept of data visualization. We can imagine that this will greatly hinder cooperation and exchanges with the common progress during actual work.In this paper, the concept and interpretation of data visualization under the background of big data era will be discussed. While only after a precise understanding of the essence of data visualization can its principles and methods be rationally used to conduct research, uncovering the implied value behind data.
