Research on Visualization of Air Pollution Characteristics and Distribution

Air pollution is increasing serious in our country. In order to help understand the characteristics and laws of the air pollution, and to study the air pollution governance, based on information visualization technology and air quality information data, combined with Html5, JavaScript and D3 programming interface, visualize and analyze the characteristics and distribution of air pollution in China. In order to grasp the real-time air pollution status of each city, the city air quality data information is displayed in real time in the same chart. In order to reflect the change of the contribution of each parameter to air quality and the change trend of each parameter with time, display air pollution situation of each city and the parameters of air pollution in real time. In order to reflect the city's air pollution over time trends and urban air pollution and geographical location, compare and visualize the air data information between cities. The results of this paper will help our residents, the environmental professionals, urban construction decision-making departments to understand air pollution characteristics and distribution of cities, strengthen the consciousness of environmental protection, and then control the air pollution.
