These graphs display the absolute number of cumulative cases, deaths, and recoveries nationally, by day (left) and daily new cases in the U.S. Hovering over the graph will display the daily values on a given day. You can adjust the lower and upper bounds of the time interval displayed using the slider below the graph.
These graphs display the cumulative cases and deaths, by state and day. A flattening of the curves indicates a slowing of disease spread or deaths. Hovering over a state’s line will tell you the number of deaths or cases on a given day. You can adjust the lower and upper bounds of the time interval displayed using the slider below the graph.
These sortable tables display the current number of cumulative cases and deaths by state, both in terms of absolute numbers and population-adjusted numbers (per 10,000 population). By clicking on the arrows in the column heading cells, you can sort states alphabetically or by population or the number of cases or deaths from high or low. You can also click through the tables using the navigation buttons along the bottom of the table.
These graphs show the daily growth in cases and deaths, as a percent of the previous day’s cumulative values. For example, the daily growth in cases is calculated by taking new cases today/yesterday’s cumulative cases x 100.
These lines can jump around a lot when the cumulative number of cases or deaths is small, because even small daily changes represent substantial growth. To help reduce such extreme fluctuations, we selected 500 as a starting value for cumulative cases and 100 as a starting value for cumulative deaths. If a state has not reached 500 cumulative cases or 100 deaths yet, it will not have a trend line on the respective graph.
To create insights from growth charts, you can select specific states or territories by clicking the name of the state and can quickly unselect all using the Clear Selection button. Hovering over a state’s line will tell you the cumulative cases or deaths on a given day, the number of new cases or deaths reported that day, and the percentage growth compared to yesterday’s reported cumulative value. You can adjust the lower and upper bounds of the time interval displayed using the slider below the graph.
Let’s use Alabama as an example of what can be gleaned from a daily growth graph. In the Cases graph, the first data point appears on March 26. On that day, Alabama had 136 new cases and its cumulative cases reached 517. That represents a 36% growth from the day before. On March 27, there were 70 new confirmed cases, bringing the cumulative cases to 587 -- a 14% growth over the day before.
Even small growth rates can represent substantial growth. If we are slowing the spread of COVID-19, we want to see the growth rates trend down toward zero.

Green percentages represent a decline in cases or deaths from the prior seven day period. By clicking on the arrows in the column heading cells, you can sort states alphabetically or the numeric values for each column from high or low.

Welcome to our COVID-19 data visualisation dashboard.
The abundance of information available about COVID-19 can make it difficult to follow the numbers and understand their meaning. You may have your own questions. So we created this portal where you can interact with COVID-19 monitoring data by changing the parameters to fit your learning needs.
Using data from Johns Hopkins University, The COVID Tracking Project, Covid-19 US state policy database and the United States Census Bureau, this dashboard allows you to explore state-level trends in cumulative and new COVID-19 cases and deaths, including population-adjusted rates. We incorporated advanced interactive features that provide you with a variety of ways to dissect the data. Maps and graphs have user-navigated and automatized time lapse and time interval widgets and “click-to-filter” features, chart zoom, and tooltips. These features allow you to utilize temporary filter values to create new insights. You can view the data from a big picture perspective or zoom into the details, as well as adjust the displayed information when you hover over with your mouse or click on a chart or map segment.
The COVID-19 data are updated daily at 3am Eastern Standard Time. Data posted at 3am today were collected/reported through yesterday. We will incorporate further disaggregated data, such as by county or demographic characteristics, as reliable data become available.
