Is your feature request related to a problem? Please describe.
If yes, I was working with the Model for Ecuador data. If it is possible include it I would lile to contribute.

Describe the solution you'd like
Now I reproduced the full script and I generated the charts for Ecuador.

• I am using the official report of Ecuador Government (for dates of interventions, death and confirmed new cases) and OMS data,
• I am using data for groups of age of Ecuador.
• Finally I changed label chart to Spanish.

Describe alternatives you've considered
For translation I just changed the labels.
