During the 2020 Coronavirus pandemic, you've probably formed a great appreciation for good, informative graphics. Good graphics can help you get a handle on thousands of individual data values, see the geographical distribution, or look for trends. 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
I'm a bit of a boat paddling enthusiast, as you might have guessed from some of my previous paddling blog posts. The amount of exertion in race-paddling is similar to running - the longest race I've paddled in a race so far was 13 miles (half-marathon distance). But in the
There are many ways to add more "visual impact" to your maps. Some techniques grab the users' attention, but often don't add anything useful to the message the map is trying to convey (such as 3D tricks, or flashy/gratuitous images and infographics). I encourage you to design maps that have
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
I've read several articles that mentioned the north magnetic pole has been moving more in the past few decades, than in the previous few hundred years. And as a Map Guy, I knew I just had to plot this data on a map, and see it for myself! I provide
The coronavirus has been a big item in the news lately - it's a pneumonia-like illness that has killed several people. It's thought to have started in China, and has spread to several other countries (including at least one case in the U.S.). The World Health Organization says the coronavirus
The flu season has started here in the U.S., and according to the Centers for Disease Control and Prevention (CDC) data it has caused 214 deaths in the first week of 2020. Is this number higher, or lower, than usual? When does the flu season start, and how long does
As I get older, a few of my buddies are starting to retire. And this makes me think about my own retirement (not that I'm anywhere near old enough to retire, mind you!) Therefore when I saw a list of the "Best & Worst Cities for Retiring" it caught my
If someone proposes a bet to you, then you should be suspicious that they already know they're going to win. And one frequent topic of such bets is the weather... What if I bet you there's a city in Canada with a warmer average January temperature than Raleigh, NC? You
Do you find yourself on the road during the holidays, and looking for a place to eat that's still open? Or perhaps you're like me - I don't cook at home, and I'm not really into visiting family for the holidays and eating with them. Well then, you probably know
The Rise of Skywalker, the final movie in the third set of the three Star Wars trilogies, will finally be released tomorrow (December 20, 2019). That's 9 movies, in about 42 years. And, if the first movies aren't still fresh in your mind (or perhaps you weren't even born when
I saw an article that claimed Donald Trump recently tweeted 123 times in one day. This got me wondering how many times he typically tweets during a day, and whether this number has changed over the years. This seems like it might be a good topic to analyze with a
I can tell that my area (Wake county, NC) has a growing population, because the traffic keeps getting worse and worse. But it's a little difficult to quantitatively gauge growth by looking at traffic congestion. Therefore let's have a look at a more direct measurement - the actual population data!
As we're getting into December, and the weather is getting colder, I thought it would be cool to plot some Antarctica data. You might remember I did this about 1.5 years ago, using good-old Proc Gmap, a special projection, and lots of tricky annotation. Well, this time let's use the
If you don't have a SAS/Graph license, then you're probably using the ODS Graphics 'sg' procedures that come with Base SAS to create your graphs and maps. And if you've tried plotting data on a map, you probably noticed that SGmap lets you overlay point-data on an OpenStreetmap, but you
North Carolina recently re-drew the congressional district boundaries for the upcoming 2020 election. Here's a copy of the new map, from the ncleg.gov website: A couple of years ago, I created an enhanced version of the 2016/18 map, and I thought I'd do the same for the new 2020 map...
The English language can be a bit tough to learn. One reason is that sometimes words can have more than one meaning. For example, the word shady can mean "of doubtful honesty or legality," or it can mean "giving shade from sunlight." Which of those meanings am I thinking about,
I recently saw in several social media posts that sales of vinyl records are forecast to be higher than sales of CDs this year (2019) for the first time since 1986. Two questions came to mind - 1) Is this true? and 2) Is this a big deal? Let's analyze
With all this sitting at a desk writing code, I have to do something to keep in shape. And for me, that something is paddling boats ... as fast as I can - and occasionally trying to race them. This past weekend I entered the race at Hunting Island, SC.
I was recently reading David Mintz's excellent SESUG 2018 conference paper on Five Crazy Good Visualizations and How to Plot Them, and saw a map that caught my eye. David showed how to create a similar map, but with completely different data - I decided to try creating a map
Eliud Kipchoge recently ran a marathon in under 2 hours. It was a special marathon where they had set up the best possible conditions to help him achieve this goal (such as swapping in pace-setting runners to block the wind for him), so it won't count as the world record
You've probably heard of the stupid 'challenges' where people usually end up hurting themselves (cinnamon challenge, Carolina reaper pepper challenge, etc). I thought it might be more helpful to society to have a challenge that could actually help people, rather than hurting them! Therefore I came up with the Halloween
The SAS Championship golf tournament is happening this week, here in Cary, North Carolina! If you're following along and watching the scores, you might wonder how they're doing compared to past years, and what kind of scores it generally takes to win. Follow along as I plot the data from
We've had record high 90+ degree temperatures here in the southeast US this past week (September / October), and it has made me appreciate having an air conditioner. Indeed, air conditioners were pretty much invented here in North Carolina (see Eric Cramer). They are used in pretty much every building
Lately we've been hearing a lot about "record low unemployment" in the news. Being a data guy, I wanted to see it for myself. Follow along as I create some custom unemployment graphs from the official data for California and New York (two of our most populous states). Or, if
North Carolina is one of those key "swing states" that might possibly decide a national presidential election. And with such an election coming up next year (2020), I thought I would have a look at the voter registration data to see how it has changed since the previous presidential election
Yesterday we had a 'special election' here in NC, to elect new members to the House of Representatives for Congressional Districts 3 and 9. The election got a lot of national news coverage, therefore I thought people might like seeing the results plotted on a map. Before I decided to
