Covid-19 Data Dashboard

Written by Said Zazai

According to the Government of Canada website “Coronaviruses are a large family of viruses. Some cause illness in people and others cause illness in animals. Human coronaviruses are common and are typically associated with mild illnesses, similar to the common cold. COVID-19 is a new disease that has not been previously identified in humans. Rarely, animal coronaviruses can infect people, and more rarely, these can then spread from person to person through close contact.”

The World Health Organization (WHO) has declared the disease a global pandemic so it becomes very important for us to have access to the right and most recent data and statistics on this disease. I have developed a dashboard that will provide some visualizations on some of the core measures that WHO, Johns Hopkins, World Bank and many other organizations publish as raw data. These measures are;

  • Total number of confirmed cases
  • New cases
  • Total number of deaths
  • New deaths

While it is critical to be sensitive towards the inferences that Data Scientists will be generating at this stage, the number of deaths to number of cases ratio does provide us a useful measure. This measure, which is the leftmost bar chart in the “Cases” and “Deaths” pages, tells us about the recovery of patients in each country. Italy with 11.1 number of confirmed cases to 1 death ratio is low of the top 10 countries with most number of deaths.


The data used in this dashboard is provided by WHO and updates automatically & daily at 00:00 CET / 19:00 EST.


The dashboard is developed in Microsoft Power BI and is published for general public consumption. To make best use of the dashboard, hover mouse pointer over each visualization and click on “focus” icon to expand the graph. Popup windows will appear when you hover over a data point that will provide the same data point in a textual format.
