‘Compare Countries’ page of the report can be used to compare how number of cases and deaths is growing in one country compare to another country. Epidemic is starting in different countries in different time and because of that a slider is available to shift timelines. The slider can be used to start both graphs from a day when there were X or more cases in each country.
Timeline is shifted: each pair of columns represent data for Spain on a certain day and data for Italy 9 days earlier.
The graph tells us that epidemic is growing in Spain (by number of deaths daily) even a bit faster than it was growing in Italy 9 days ago.
