The Most Common 4-digit PIN numbers
Pin Point: The Most Common 4-digit PIN numbers by Information is Beautiful was a redesign of Nick Berry’s original work. Having a pin that’s easy for you to remember, could also be an easy one to guess. Check out this infographic and see how safe your favorite PIN may be.
Chip and PIN card, phone passcode, hotel safe – how predictable is your chosen PIN number?
3.4 million data points visualized from several data breaches.
Created by the late great Nick Berry of Data Genetics (redesigned and used with permission). He wrote a great data story around this which is also worth a read.
I really like this heatmap. Visually, it reveals a number of insights from the data:
The diagonal line shows the PINs where two digits are repeated to create a 4-digit PIN. 1111, 3434, 5050, etc.
The lower left corner is brighter with PINs starting with low numbers, generally representing dates. The section goes to the right up to the number 31, representing the day. Birthdays, anniversaries, etc.
There is a bright horizontal line of PINs starting with “19” the wraps into a line starting with “20”, representing a year that someone has chosen for some significance. Birth year, wedding, graduation, etc.
The black squares are the least used PIN numbers, also listed at the bottom of the infographic.

The Mammoth Cost of Operating America's Combat Aircraft
The Mammoth Cost of Operating America’s Combat Aircraft shows the operating cost per aircraft in 2018. Statista created this infographic when the non-partisan U.S. Government Accountability Office (GAO) released an overview of mission capable rates and the cost of operating U.S. military aircraft in 2020. Over 40 aircrafts were examined, Statista chose to highlight these 15 in their infographic.
The non-partisan U.S. Government Accountability Office (GAO) recently released an overview of mission capable rates and the cost of operating U.S. military aircraft. It examined more than 40 different aircraft types, finding that only three of them reached their mission capable goals between fiscal years 2011 and 2019. In total, the report put the collective cost of operating all of the U.S. military's aircraft fleets at $49 billion in fiscal year 2018, taking operational & support (O&S) costs such as maintenance as well as supply support in account. O&S generally makes up 70 percent of a weapon system's total life cycle costs and it includes spare parts, depot and field maintenance, contract services, engineering support and personnel, amongst other factors.
It would be nice to see how many we have in service too. The stacked bars work well. As a reader you can tell the values between operating/support and maintenance, but the total is what matters.

The Quickest Route to Washington DC
The Quickest Route to Washington DC is a GIS visualization from @ArterialMapping (also known as MattMDL on reddit)
From @ArterialMapping :
How was this map completed? Well, using @Esri ArcGIS Pro Network Analysis toolset ! In general terms, there were 4 steps:
1. Created a dot grid for the whole of the continental U.S. This grid is what enables the routes to be created to D.C. A dot was also created for D.C.
2. Run Network Analysis to find the shortest route to D.C. from each dot.
3. Run a calculation for the number of overlapping routes (shown as the stronger strokes on the roadways)
4. Then, of the 4 main spokes I saw, I copied them over into their own layers and colored them accordingly.
Red generally follows I-70 to I-270, Green generally follows I-81 to I-66, Blue generally follows I-95 south of D.C., Orange generally follows I-95 north of D.C.

America’s Immigration Crisis sankey diagram
I really like this Sankey Diagram explanation of the numbers behind one of this year’s hottest political topics in the U.S.: How to Fix America’s Immigration Crisis. The original article adds a scrolly-telling element that makes it even better by slowly revealing each branch and explaining the data.
I know this article is hidden behind the NY Times paywall. If you’re not a NY Times subscriber you can try to view the original article with this LINK or try using reader mode on your browser. Let me know if this link doesn’t work, and I’ll try to post a new one.

The Problem with Plastics
This infographic shares the depressing small amount of plastic that gets recycled. Information is Beautiful created The Problem with Plastics infographic by visualizing data by Geyer et al, Science Advances, back in 2017. The infographic uses a Sankey Diagram to show the fate of all plastics that were ever made.
Why plastic recycling doesn’t work 🙁
“Most ‘recycled’ plastic still ends up being dumped or incinerated”
n.b. These numbers are from 2017. Humanity produces approx. 345 million tonnes of plastic a year. That means another ~1.7 billion tonnes since this study was released.

Timeline of Reddit
Vizion Online created a Timeline of Reddit to give a better understanding of the platform.
Most of us have come across Reddit at some point but what do we really know about this hugely popular social networking platform?
It was conceived in America in 2005 as a news forum where it became popular with prominently a younger well educated profile, sharing topics, links and images, allowing users and communities to comment on each post.
Reddit has grown to be a prevalent news forum where members vote on content giving them ratings. Although Reddit is considered a social media platform it is a unique network centred around communities and subgroups known as subreddits.
Throughout its history, there has been a number of high-profile stories including activist protest and political coverage.
We have created this infographic to give a better understanding of the platform using a timeline of key events throughout the history of Reddit.
Personally, I don’t like timelines designed this way. I prefer to see the events spaced out chronologically to match an actual timeline instead of each event equally spaced. If three events happen in the same year, I would list them in the same box. Only one box per year.

How to Safety Thaw a Turkey
Addressing a common, annual problem, the U.S. Department of Agriculture put out this 3 Ways to Thaw a Turkey infographic in 2016.
While frozen, a turkey is safe indefinitely. As soon as it begins to thaw, bacteria that may have been present before freezing will begin to grow again. There are three safe ways to defrost a turkey: in the refrigerator, in cold water, and in a microwave oven.
Informative infographics that answer common questions are some of the most popular infographics.
In my book, I also talk about the Online Lifespan of an infographic, and this infographic has a fantastic Online Lifespan as it covers an evergreen topic and becomes popular every year.

10th Anniversary of the Cool Infographics Book (Part 1)
Ten years ago today, the Cool Infographics book was released on October 28, 2013. I frequently lament that it’s nice to have written a book, but the actual process of writing a book was pretty difficult.
I never set out to write a book. Wiley publishing approached me in 2011, and convinced me to turn the talk I was presenting at conferences into the outline for a new book. I had started my infographics design company, InfoNewt, in 2010, and was giving almost monthly presentations about my process to design, publish and promote infographics. Turns out that the talk outline did lend itself nicely to the structure of what became the Cool Infographics chapters.
Looking back, there were a number of unique challenges that I had to solve while putting together the book, and some were also new issues for Wiley.
Permissions to include infographicsI didn’t design most of the infographics I included in the book, because this wasn’t a book of self promotion. My goal was to share the best designs from the world of infographics as examples, and that meant including designs from some of the best designers in the world.
Here was my challenge. Most infographics are meant to be shared and reposted as much as possible online. “Going viral” was the ultimate achievement of an infographic. However, legally reprinting an infographic in a book required the explicit, signed permission of each infographic’s copyright holder. I ended up including over 100 infographic examples in the book, which was a lot of negotiation and legwork.
For every design I included, I had to track down the designer or publishing company, and get them to sign an official permission form that allowed me to include their design. I wasn’t able to include many of the designs I wanted to share because either I couldn’t track down the original designer, or they refused to sign the permission form.
Infographics are large
The online infographics that I was writing about were much larger that what could effectively be shown on the 7.3 x 9.2 inch pages of the book. They had to be reduced to fit on the pages, which made the text in many of them unreadable when sized to the book’s pages. Wiley didn’t want to publish a larger format book, so I had to come up with another idea.
My solution was that every design I included, also included a link to view the original infographic online. The downside was that readers can’t click a link in a printed book. That meant they would have to manually type in the URL, and many of the links were really long and complicated addresses. So, I created over 100 shortened links for the book, using my hosting platform from the coolinfographics.com website.
For example:
Link in the book: Coolinfographics.com/Figure-5-19
Forwards to the long original URL: http://create.mcgraw-hill.com/wordpress-mu/connectblog/files/2012/03/McGraw-Hill-Connect-Handout-WHITE-Small.jpg
See what I mean? No one was ever going to try to type in that long URL.
I also created an index web page for all of the Figures that had clickable links for every design in the book that is available to see online: coolinfographics.com/figures
Making the book navigation visualInfographics is a very visual topic. Not only do readers want to see the visual examples of every concept I discuss in the book, but I wanted the book itself to be visual too. This took some negotiating with Wiley to make happen. Every chapter has its own color, and I included that color on every page in a small tab that prints all the way to what is called the “fore edge” of the page. This makes the color visible at the edges of the pages even when the book is closed. These tabs are staggered down the page to provide an easy navigation to find the color you see in the Table of Contents.
Marketing was my job
It turns out that most book publishing companies are very focused on publishing, printing and distributing a book, but not so much on marketing them once they get printed. Once a book is published they move on to publishing the next book, and the majority of promoting my book fell to me. This was something I didn’t expect. I am constantly teaching people that designing and publishing an infographic isn’t enough, and you have to promote it too. I wrote a whole chapter about in the Cool Infographics book! Similarly, I expected a big book publisher to be good at the promotion process for books. I was wrong. They printed a beautiful color book and got it into Amazon and onto the shelves at bookstores like Barnes & Noble, but that’s where their effort mostly ended.
Most of the promotion for the book has come from me. Whether it was one of my talks, a guest appearance on a podcast, an article that mentioned the book (like this one) or someone using Google to search for infographics and finding the Cool Infographics website.
Where to go from here?The book has done really well for 10 years, and sales continue. The concepts I wrote about in the book are all just as relevant now, as they were 10 years ago. However, some of the example designs are out-of-date, and some of the design tools aren’t around anymore.
Where do you think we should from here? As readers of the Cool Infographics website and book, what would you like to see as ongoing content exploring the design, publishing and promotion of infographics? Videos, workshops, articles, tutorials, online courses, etc. Post a question, comment, or idea and let me know how Cool Infographics can be relevant to you in the future.
I’d love to hear from you. Either post a comment below or send me a note through the CONTACT page.

Annular Eclipse
Kennth Field used Nasa’s data to create this Annular Eclipse infographic. The graphic combines the information of where the eclipse had its highest coverage, as well as the time of day it was at its peak. It also shares the direct path of the moon and some basic information on what an eclipse is.
Overall, a beautiful summary with very little verbiage. In only a few seconds, you could tell how obscured the Sun was going to be in your part of the U.S.
Thanks for RJ Andrews for bringing this graphic to our attention!
