Abstract
Information on coronavirus disease 2019 (COVID-19) has been a significant focus for the global public since the outbreak of the disease. In response, data visualization has become the main form of media used to inform the public about the global pandemic’s progress. This paper studies the example of China, the main country affected by the virus in the early stage of the pandemic, to explain the problems regarding the differences in time, knowledge, and technology for information transmission. This paper also tries to explain the causes behind the dissemination of rumors, misjudgment of the public, and the difficulties of perception regarding pandemic information based on the three aspects of information collection, processing, and presentation. We argue that comprehensive information transmission with direct and clear visual presentation could help the public better understand the development of the pandemic, relieve social panic, and help authorities promptly adjust public health policies to absorb the social and economic impacts of the pandemic. Based on a case study, we propose that hierarchical presentation, comprehensive descriptions, and accurate visualizations of pandemic data can effectively improve information transmission, thus providing helpful references for authorities and organizations to improve the effectiveness of pandemic information transmission.

Summary
At the end of 2019, coronavirus disease 2019 (COVID-19) became a global public healthcare emergency. This study found that the three strategies of the hierarchical presentation of data, the comprehensive description of information, and the accurate expression of visualization can improve the status of information collection, information processing, and information presentation in the information transmission model. Can these factors improve the transparency of pandemic information, correct the audience’s misunderstanding, and enhance the public’s awareness of prevention, but they can improve measures of pandemic prevention and control to make them more scientific, precise, and efficient for government. With the COVID-19 pandemic still raging around the world, this argument has important practical significance
