1. Use the dataset by of covid 19 by WHO at https://covid19.who.int/WHO-COVID-19-global-data.csv. Find the three countries with the most numbers of deaths by Covid-19.

Hint:

• Pipe with arrange(-Cumulative_deaths) to rank the data by the number of cumulative deaths

2. Use transition_reveal to make a plot revealing the number of deaths in the three countries with the most numbers of deaths

3. Create the new variable (column) death_per_cases recording the number of deaths per cases (Hint: divide cumulative deaths by cumulative cases). What are the three countries with the highest deaths per cases?

4. Use transition_reveal to make a plot revealing the number of deaths per cases of the US, Italy and Mexico.

5. Import the following data https://raw.githubusercontent.com/owid/covid-19-data/master/public/data/vaccinations/vaccinations.csv

Use transition_reveal to plot the total vaccinations per hundred by level of income. Hint: the levels of income are identified in the location variable. Put a short comment on the caption of the plot.
