These graphs work best on a computer. Phones, not so well. Phone users: check out the blog.

These graphs are interactive (and not very useful or intelligible if viewed without interacting). You can click-and-drag to zoom, single-click on a particular item to turn it on or off, or double-click to show just that item.

### Severity

The following graph attempts to show broadly “how bad” the epidemic is in each state, based on daily cases. It does this by multiplying-daily-cases-per million (DCPM), by the week-over-week growth factor in new cases (DCPM and growth are graphed separately farther below). Over 100 is a “severity warmspot” (bad); over 200 is a “severity hotspot” (very bad). Here are the top 20 states:

And for all states:

### Total Cases

### Daily Cases

##### Daily Cases Per Million People

To really compare the numbers of different regions, we need to adjust for population. Hence “daily cases per million” (DCPM), which lets us see how *relatively* bad a region has it. I define a region as “warm” if DCMP is more than 100, and “hot” if DCPM is more than 200. You’ll definitely want to click-and-drag to zoom in to the busy part of this graph, since there are a few wild outliers that smash everything to the bottom:

The graph below is similar but shows all states, and shows the moving average rather than the individual days with trendline (top 20 states):

And for all states:

##### Daily Cases Trajectories

The next graph shows the relative trajectories in daily-cases-per-million of the states, in days since each state reached 100 DCPM (those that haven’t are not shown). So each state’s graph is *shifted* in time, so they align horizontally at the moment they reached 100 DCPM:

##### Daily Cases Growth

This next graph is the “rope chart,” which shows the daily growth of new cases each region. This allows to predict the direction a region is headed. When a line crosses zero headed downward, that region has turned the corner toward recovery. I define a region as “warm” if growth is greater than 1%, and “hot” if growth is greater than 5%. Remember that you can double-click a name at the right, to see a graph of just that region. Here again you’ll probably want to zoom in with click-and-drag to see the details better:

This next graph is similar to the rope chart, in that it shows percent growth. But rather than fitting a broad trendline, it uses a smoothed moving average, to show more of the fine details of the trajectories of each state.

And the same for all states:

### Hospitalizations

Hospitalizations per million, for all states, as a 7-day moving average:

### Deaths

##### Daily Deaths Per Million People

### Testing

##### Percent Tested

##### Percent Positive

This measures how many tests come back positive. For comparison, a positive test percentage of less than 8%, is considered good enough to reopen, by the state of California.

Here are the positive test rates, for all states, shown as a 7-day moving average, which shows the short-term trends much more than the broad trendline above. Less than 8% is doing OK; less than 2% is very good:
