Graphic Analysis COVID

Code to perform a descriptive analysis of Virus COVID-19 in each country.

Features

Code to perform a descriptive analysis of the virus behavior in different countries;
The analysis is divided into confirmed cases of the COVID-19 virus and the deaths caused by this virus;
The data used to perform the analyzes are those provided by Johns Hopkins University;
The graphic analyzes performed are:
- Virus behavior and evolution of cases of death by countries;
- Comparison of confirmed cases of the virus and deaths caused by different countries;
- The behavior of new cases of the virus daily with the moving average (simple moving average, SMA, and exponential moving average EMA);
- The behavior of new deaths daily with the moving average (simple moving average, SMA, and exponential moving average EMA);
- The behavior of the simple moving average (SMA) and standard deviation for new cases and confirmed deaths per day.

The code has seven functions, three functions are for data processing and four for analysis. These functions are:

data_preparation: Function to load the data to be analyzed;
data_country: Function to create a matrix with data of confirmed cases of COVID-19 and death by COVID-19;
data_per_day: Function to calculate the newly registered cases of the COVID-19 virus and the newly registered deaths;
country_plot: Function to plot the data of COVID-19 confirmed cases and deaths by COVID-19 in the same plot;
comparison_plots: Function to compare the behavior of the COVID-19 virus in different countries;
new_cases_per_day: Function to graph the new confirmed cases of the COVID-19 virus and the new deaths caused by the virus;
new_cases_per_day_fill_plot: Function to graph the moving average and standard deviation for newly registered cases of COVID-19 and new deaths registered per day.
