Visualization for COVID-19

This website is designated to list tutorials about various ways and tools of visualizing COVID-19. Materials on this page are being updated. Please check back for new resources periodically. 

Visualizing confirmed cases by state

This video shows you how to create a map of confirmed cases by state (see the map below) in minutes.

You will learn how to improve this map in following video.

Sources of data used in this video: state boundary, confirmed cases (source 1 and source 2).

The map we made last time does not have a legend. This time we add legend to the map. Check out this  video.

This time we use a business intelligence software called Tableau to map confirmed cases. Check out the video here.

This time we explore three different ways of classifying the confirmed cases and how these different ways impact the appearance of a maps. Here is the video

Natural Breaks: (A.K.A) Jenks method: it minimizes the squared deviations to the class means.‚Äč

Quantile: Each class contains the same number of features (e.g., states in this case).

undefined

Equal Interval: Grouping observations by using class intervals of an equal range (e.g., 1-25, 26-50, 51-75, 76-100).

Maps we have made so far have a problem. Alaska looks larger than it should be compared to the continent of U.S. In addition, there are large space between Alaska or Hawaii and the continent of U.S. This  video introduces you how to fix these problems by adding new data frames.
