The data used for producing the charts can be referenced in the 'data-*' repositories of the coviz-org group on gitlab.com. This data originated from the following sources:


The models on this website take the historical data on the spread of the coronavirus and extrapolate them to attempt to predict the future. Of course, these models are guesswork.

The algorithms used in these models are open-source and contributed by the community. The community who submitted these algorithms may not be doctors, statisticians, data scientists, etc. The models may be wildly innaccurate and are provided without any warranty of any kind.
