New Visualization Shows How Long Angela Merkel Has Been in Office Compared to Other World Leaders
We discovered this simple and elegant visualization on Reddit, which was originally created by reddit user pierrebrt. He created the artwork for French newspaper Le Monde. It utilizes clean line work and bold colors to visualize how long chancellor Angela Merkel has been in office compared to other world leaders.

So, how long has Angela Merkel been chancellor? She was first elected in 2005, re-elected in 2009, 2013, and 2018. She is the first woman to be elected chancellor, and in 2014, she became the longest-serving head of government in the European Union. In 2021, she decided not to run again, which is historical in that it is the first time since the founding of the Federal Republic of Germany that the incumbent chancellor has not pursued reelection. Despite her incredibly long tenure, Pew Research Center found that confidence in her leadership is at an all-time high during her last full year in office.
The overall appearance of the graphic is stunning; the vertical lines suit the formal nature of the topic while the masterfully chosen cascade of colors captivates the audience. It conveys a lot of information quickly and effectively, and would make an excellent poster for anyone politically inclined. We also love the use of small flags to indicate the countries, and helpful numbers at the bottom as a quick reference guide to how many leaders that country has had throughout Merkel’s duration in office. Who knew politics could be so beautiful and pure?

New Research Shows Which Vehicle Makes and Models are Deadliest
Fatal accidents are all too common in the United States, but some crucial factors can affect whether an accident becomes deadly. One of those factors is the safety features of the vehicles involved. Makes and models aren’t equally safe, and the research conducted by the team at Convoy Car Shipping makes this grim fact clear.
The research used data from government organizations to study the statistics on which vehicles were involved in fatal accidents and how many fatal accidents a given vehicle was involved in compared to number of them on the road. The results give us a balanced look at which makes and models have the worst track record of fatal accidents.

The research shows that these vehicles are the deadliest:
- Ford Ranger
- Jeep Cherokee
- Dodge Charger
- Nissan Maxima
- Ford Taurus
- Ford Mustang
- Chevrolet Camaro
- Chevrolet Blazer/Tahoe
- Chevrolet Silverado
- Ford Expedition
American-made vehicles aren’t looking safe when we consider the number of Ford and Chevy models on this top ten list. Examine the data to find information on even more vehicles. You’ll also see that this make/model list differs from overall crash statistics. The broader picture proved Harley Davidson motorcycles to be the second most deadly vehicles. We think that this skews the story the data tells because motorcycles have far fewer safety features than cars and trucks. The team at Convoy Car Shipping should be applauded for their attention to detail that considers the unequal safety standard on cars and trucks versus motorcycles. The research gives us all possible data so that vehicle owners can draw their own conclusions.

Visualizing the Cost Per Ounce of the World’s Most Valuable Metals
The team at Kylar Mack shows us just how valuable the world’s most precious metals are with this illustrated chart visualizing the cost per ounce of the most expensive metals and alloys. A metal is naturally occurring, and many appear on the periodic table of elements whereas an alloy combines two elements.
On this illustrated chart, we can truly visualize the comparative value of these metals because the team stacked money representative of the value beside an image of each metal. The chart is a great example of the power of visual data. Our eye is immediately drawn to the vast stacks of cash beside the most valuable metal, Californium. These stacks tower above ever other metal on the chart making it clear that not all metals are created equal.

Californium’s value is a shocking $765,436,299 per ounce! That’s significantly higher than the second-most popular metal, a non-synthetic called Iridium, which is valued at $4,700. The key to the value difference lies in the fact that Californium is a synthetic substance. It’s created in a nuclear reactor and only two plants in the world have the capability of engineering it. As for Iridium, it’s naturally occurring but hard to mine and access. It’s found deep under the Earth’s crust, often attached to asteroids. Through this chart, we can learn more about different metals as well as why they’re so highly valued. Many are needed for key electronics and aerospace parts.

Mapping Spam Call Hot Spots Around the Country
Spam calls are a widespread problem that can be a nuisance or leave important information vulnerable to scammers. This map from Ooma shows us that although spam calls are widespread, they seem to have concentrated hot spots around the nation.
The Ooma team used data from the Federal Communications Commission to pinpoint where the highest number of spam calls are occurring. The data is based on the number of spam call complaints the FCC receives per capita. The team highlighted each city with the highest number of calls and shows in a graph below the map how many spam calls complaints are received per 1,000 people. The map is a detailed look at where spam calls are concentrated, giving us an interesting look at the data. If you live near one of these hot spots, be wary of answering the phone.

Alexandria, Virginia, tops the list with the highest number of spam call complaints. The city has received so many that local police have had to put out spam call warnings and prevention tips. Seeing such high concentrations of spam calls definitely leads to interesting questions about why these areas might receive more calls than others.
