Now the development of network and intelligent application have become a major label of modern city, contributing tremendous strength to all parts of modern city operation. It can be said that the application and integration ability of urban network represents the influence of this modern city. Here, the value of urban network centrality represents the application and integration ability of the urban network, that is to say, the centrality of urban network represents the size of a city's influence.

Based on the viewpoint above, we retrieve the corresponding data content on the Internet and find the original data on FigShare's Open Data Sharing Platform (https://figshare.com/). Some of the data are previewed as follows:

In this data set, we believe that the most attractive feature is the comparison of the differences between the urban network centrality in the same era and the change of the urban network centrality data in different times. From the former, we can see the differences of the development of science and technology in cities, while the latter gives a quantitative description of the development process of science and technology in cities. Therefore, in the process of data presentation, we focus on these two points to do an artistic processing.

We choose installation art and visual art as two forms of presentation, in which installation art shows the increase of network centrality between cities through three-dimensional sculpture, while video shows both.

In terms of shape selection, we think that urban centrality is an index to measure the influence of a city. It is very reasonable to abstract it into a circle, in which the outer radius of the circle represents the degree centrality and the width of the circle represents the size of the intermediate centrality. The visual symbols of the circle can well artistically reflect the intrinsic meaning of its data; at the same time, we also think of the sphere, which has a strong visual impact along the normal line, while giving people the trend of outward expansion, the combination of two evidences, complement each other.
