Use of Data Visualization to Defeat COVID-19

In the early days and weeks of any global health concern, particularly in a fast-moving outbreak such as  the coronavirus, many unknowns exist. However, data visualization unblurs those unknowns as comprehending trends and combining data points unveil a story filled with insight. The ability to visualize the spread of the coronavirus can help raise awareness, understand its impact, and ultimately, assist in prevention efforts.

In addition to speeding up the virus vaccine research and strengthening personnel mobility management, the timely collection, transmission, and management of personnel information has also become a vital part of the battle against the coronavirus. There are huge challenges in all aspects of society such as resumption of economic and educational activities, hospital treatment, and community management.

Scientists utilized the knowledge of data visualization to design dashboards. It allows organizations to effectively monitor the pandemic situation and carry out prevention strategies. It mitigates risk by providing insight into the past, current, and expected future trends.

Our aim with this article is to provide you with a list of tools best suited for such needs and the type of dashboards you can create with them along with some sample dashboards.




Worldwide Coronavirus Outbreak Statistic | Source:



Johns Hopkins University Dashboard: The live dashboard pulls data from the WHO (World Health Organization) as well as the centers for disease control in the United States of America, China, and Europe to depict all confirmed and suspected cases of coronavirus along with the number of recovered patients and deaths. The data is visualized through a real-time graphic information system (GIS) powered by Esri.



Prevention and Control Situation Analysis Dashboard: Comprehensively analyze the prevention and control work of the hospitals experiencing the coronavirus outbreak from the dimensions of confirmed cases distribution, epidemic trend, and risk monitoring.

Community Access Analysis Dashboard: The residents of a community encounter potential risks when individuals enter and leave the community. Specifically, community epidemic prevention and control creates a direct impact on those who are most vulnerable such as the elderly population.






Some other publicly available coronavirus dashboards:


Another notable dashboard is from Information is Beautiful which provides a detailed glance at how the virus unfolded over the months. It uses features such as extensive widgets for infection trajectories and country-wide fatality rates. You can access the same at Some screenshots of the dashboard:


Other noteworthy Data Vsualization Tools:
