Respectively, the charts display the relation between: (B1) time x cases/deaths, (B2) time x tests, (B3) total cases/deaths x last week cases/deaths, and (B4) time x cases/deaths projection length. (C) Events Panel: displays information and source references concerning main events occurred in certain time periods. (D) Events Time Chart: chart presenting the policy changes of a country over time. (E) Country Cards: show information concerning the analysed group of countries, allowing the exclusion and inclusion of different countries into the analysis.
