This visualization is meant to demonstrate the exponential growth of coronavirus deaths in the United States starting in early March when the first confirmed deaths took place. Some reports indicate that the first deaths may have been as early as early February, though that is not shown in this data.
In the animation, each day is about 1 second long so on days with fewer deaths, the figures show up more slowly, while on days with greater deaths, the figures come very, very quickly.
Deaths stop growing exponentially in early April and start to level off and plateau. However, they haven’t yet started to decline significantly so we are still seeing thousands of deaths each day (as of late April).
The data and visualization will be updated daily with data from Covidtracking.com.
For more information about the virus and the disease and data collection, you can find good information on the CDC website.

Fires are once again raging in California and air quality in one of the most populated metropolitan areas in the country (the San Francisco Bay Area) is quite poor. This map show current air quality in the Bay Area. For more information see the EPA’s Air Quality website.
EPA has assigned a specific color to each AQI category to make it easier for people to understand quickly whether air pollution is reaching unhealthy levels in their communities. For example, the color orange means that conditions are "unhealthy for sensitive groups," while red means that conditions may be "unhealthy for everyone," and so on.
|Air Quality Index
Levels of Health Concern
|Good||0 to 50||Air quality is considered satisfactory, and air pollution poses little or no risk.|
|Moderate||51 to 100||Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.|
|Unhealthy for Sensitive Groups||101 to 150||Members of sensitive groups may experience health effects. The general public is not likely to be affected.|
|Unhealthy||151 to 200||Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.|
|Very Unhealthy||201 to 300||Health alert: everyone may experience more serious health effects.|
|Hazardous||301 to 500||Health warnings of emergency conditions. The entire population is more likely to be affected.|

Long-term stress has been shown to be detrimental for your health. While it’s probably not possible to completely eliminate stress from people’s lives, there are many individual choices and decisions that can influence the amount of stress that people experience, including where they live, what job they have, their socio-economic conditions etc. . . One interesting bit of data analysis looks at an aggregate level to understand how stress differs from state to state depending on specific economic, demographic and other geographic factors.
