Information Visualization Design Research Of City Public Data Under The Theory Of 'field'

As the underlying urban public data, open to the public, it means that the most basic image of the city and detailed description will will show in front of every citizen. In today's era of open source, the data can be converted into material force of society have a huge impact, contains the infinite possibility. As a kind of data visualization and information expression language, exploring, data display and expression meaning, but also a can step in urban public life, promote the city and the medium of communication. To interpreting cities,which will make citizens more multidimensional aptly feel the change and development of the city, and drive of each individual involved in the construction of city.Under the background of this topic in the information society, the more possibility of conception of urban public data visualization, with a systematic thinking, research in information visualization design, people, data, and the city(Information dissemination environment) the interaction between the relationship. In Pierre Bourdieu's "field", such a system, the linkage of structural relations theory as the research Angle of view, to convey information visualization of the physical space(geographic) associated with the nonphysical space(social environment). In the visual design of public data information constructs in the construction field, the conversion of data information and the different aspects involved in the process of communication as a whole to study, explore a kind of public data under the background of open, open design thinking logic and method of information visualization model. This paper divides the "field" information visualization design for the environment and information field, the user field, that is, a visual design with the authenticity of the information, interest and functional three features, the article will build according to their respective field in detail in this paper.The study of information visualization, is not a fresh topic, on the one hand is the study of visualization technology in the field of computer software, is designed to learn on its visual form of graphic design. Since 2008, "big data" era, bring us great social change, and with the rapid development of new media technology, people's reading habits and lifestyle change,prompted the visual design produced more contextual information and expression form.Innovation point of this subject is to, service oriented, information visualization design as a means to promote public participation in the media and to emphasize information visualization design of systemic consciousness, make the people and the places in the city(area) to form a closer emotional connection, with the data. Help designer to stand in the perspective of a more system to design the way to present data, sets up the design concept of information visualization design comprehensive thinking, information visualization design that is associated with city, promote the good atmosphere of data dialogue, to meet the needs of large data, the age of the Internet wisdom city.
