In the spring of 2020, it was supposed to be a happy time for the whole family to be reunited. The sudden outbreak of new coronavirus pneumonia cast a shadow over the Spring Festival. The epidemic swept all over the country and the mountains and rivers were "sick". In the face of this situation, everyone should "bow down" and do their part to fight the epidemic. Although we cannot go deep into the front line and charge in white robes, we use the way we are good at to pray for China, cheer for the world, and fight the "epidemic" with one heart ". We use data crawling and visualization technology to obtain comprehensive information such as new and cured domestic and international epidemics in real time, and analyze and process these data information, and finally realize data visualization in the form of intuitive maps, line charts, pie charts, etc. In this anti-epidemic test without gunpowder smoke, in the face of large-scale personnel flow, big data analysis is comprehensively used to promote the cross-coordination of different data such as information exchange, social governance, epidemic prevention and control, etc., to provide important support for the fight against the epidemic, so that the people can stay indoors, control the epidemic information in real time, and effectively transmit the information to the hearts of the people. At the same time, through the power of big data, it can not only help the prevention and control of the epidemic with "wisdom", but also help social development and governance.
