Truth Data Source

The visualization aggregates daily reports containing death data from the JHU CSSE group as the gold standard reference data for deaths in the US.

Daily Truth Data CSVs

We aggregate and format both Cumulative Death and Incident Death truth data from the JHU CSSE group. Although these csvs are not explicitly used in the visualization code, they match the "Actual" line in the visualization. This python script creates these truth data csvs.

Visualization Truth Data

The Actual line in the visualization is based on the JHU CSSE group truth data. The visualization uses this Cumulative Death JSON, and this Incident Death JSON. This python script creates these JSONS.

The actual data the visualization uses (Forecasts + Truth Data) is in this folder. These JSONs are created with the commands in 0-init-vis.sh using the truth data when the visualization is built. The file called "season-latest" is the default view, which is also Cumulative Deaths. For each State key in the JSON, there is an Actual object that contains the truth data in the visualization. More on the JSON structure here.

Zoltar Truth Data

The Zoltar truth data is created with this python script and can be found here.

Truth Data Update Schedule

All truth data are updated daily with Travis CI around 6:30AM EST.
