Is your feature request related to a problem? Please describe. Since each series (Confirmed, Recovered and Deceased) are separate graphs, the best way to represent this information in DAILY TRENDS is to use bar graph.

Describe the solution you'd like In DAILY TRENDS, graphs should be a bar graph

Describe alternatives you've considered

Additional context We didn't do this initially because in the first version of the site, we had all three series together on the same plot. In that case, line graph was suitable. Now bar graph is more intuitive.
