Some claim that deaths in the US have been increasing, and some claim they have been decreasing. Which do you think is correct? Let's take a look at the data ... The Data Here in the US, the Centers for Disease Control and Prevention is a good/official source of data
"With great power comes great responsibility." I'm not sure exactly where this quote comes from, but I think everyone should keep it in mind when creating graphs and maps! There are many design decisions that can influence how the end user perceives the data in a graph. For example: The
A user commented on one of my previous maps ... "How can there be 820 cases of Coronavirus per 100,000 people? - There aren't even 100,000 people in my county!" Well, when you want to compare something like the number of COVID-19 cases between two areas that have differing populations,
Now that we are many months into the COVID-19 pandemic, we can start to reexamine the data and look for trends. This time, I want to explore how COVID-19 has been spreading around the US. I do this by animating a county map over time. What is animation? Are you
Now that we are many months into the COVID-19 pandemic, I've started going back and reexamining the data for lessons or trends (you might say hindsight is 20/20). This time, I want to explore how COVID-19 has been spreading around the US. I do this by using a graphical idea

In February, I wrote a blog post about creating a coronavirus dashboard with
If you're close to my age, you probably remember Joe Walsh's song Ordinary Average Guy. That song popped into my head when I was writing this example about moving averages, so I encourage you to listen to it while reading the blog post. Many people are looking at graphs lately
Now that COVID-19 is spreading in the US, I thought it might be helpful to view the data at a more granular level. Follow along as I plot the county data on a map and discuss how the color-binning can influence people's perception of the data. Maps like this can
Everyone's thinking about the Coronavirus Disease 2019 (COVID-19), and wondering if there are any cases near where they live. I recently used SAS Software to create a dashboard with a world map showing which countries had reported cases. And now that the virus has spread around the world, a world/country-level
The COVID-19 Coronavirus outbreak has been in the news a lot lately, and everyone is probably looking for a quick/easy way to see the data. The best visualization I've seen so far is this dashboard by Johns Hopkins. Here's a screen-capture: But before we dive into the data analysis, let's
