This code is inteded to be run every day (e.g. with cron) and creates a plot of the total COVID-19 cases in Italy versus time. The data is downloaded from the official git repository and fitted by two sigmoid functions to try to predict the overall behaviour.
The class CoronaData creates the dataframe with the data to be
plotted. The method from_git_italy downloads the data from the
git repository of the italian government. Alternatively, the data can
be loaded directly from a file with the method from_file.
The class CoronaPlot takes the data and plots it with matplotlib. The fit with two sigmoids representing the two infection waves is also done within this class. Note that for the fit to work, the discrete time data in date format is transformed into seconds format. The plot is saved as a png-file. The user can choose where it should be saved.
