Abstract

Data visualization is a science and technology research on data visual form, which is originated in the 50’s of the twentieth Century. It went from scientific visualization, information visualization to data visualization. Based on computer graphics and pictures data visualization display and reveal the main information contained in data. Data visualization contains data acquisition, data analysis, data processing and data modeling. Based on psychology the motivation of data visualization is to expand the scope of visual perception which is easier to get information than other biological perceptions while the effect is better. Modern science and technology greatly extends the human sensory “arms”. Visual perception has very long “arm” and often “robs” other perceptions’ “business”. This paper introduces the basic concept and main content of data visualization, reveals the essence of data visualization. Through the “Agricultural planning visualization” case, the technology process of data visualization applied in production has been established, which can be described as 4 steps operated by order. The first step is to determine and decompose a target. The second step is data acquisition and processing. The third step is models designing and expression. The last step is video production.

Highlights

  • It went from scientific visualization to information visualization and data visualization

  • The basic purpose of data visualization is to make the information contained in the data convey to the audience with the highest efficiency

  • The development of computer science and technology has opened a broad prospect for data visualization

Summary

Introduction

As a kind of technology, visualization applied to the scientific research and production practice leads to many research and practice fields[1][2][3][4][5][6][7]. Data visualization is a science and technology research on data visual form, which is originated in the 50's of the twentieth Century. Is a digital form to create a visual image, help people understand the science and technology concept or result using computer graphics. Information visualization rising in 1990s was born in scientific visualization, which emphasizes to express the abstract information using computer graphics and images. The term of data visualization covering the fields of scientific visualization and information visualization was born in 2000s. Based on computer graphics and images data visualization display and reveal the main information contained in data[2]. Data visualization is applied to scientific research, and widely used in production practice. Data visualization is mainly the process of research activities in scientific research while it is the result of productive labor in practice. The result of production can be called intellectual products which maybe is a report expected to visually expressed
