Police brutality cases are a serious topic in the United States right now. Multiple instances of deadly use of force in recent times has reopened the debate about racism and police brutality. Police killing statistics for black people are particularly dire. Since 2013, black people make up 28% of victims killed by police, despite being only 15% of the U.S. population.

The main visualization is a unique radial histogram. A radial histogram, also known as a circular histogram, is a variation of the traditional linear bar chart that displays data around a circle. This allows more data to be displayed than a linear bar chart. The outer bars represent the average annual police homicide rate per 1 million citizens, and the inner bars indicate the 25 police departments with the highest average annual police homicide rate for black people per 1 million black citizens. Beneath the radial histogram are a series of vertical bar charts outlining more details on police homicides by race.
According to the charts, the St. Louis Metropolitan Police Department has the highest average annual police homicide rate with 17.9 per 1 million citizens. They are also the police department with the sixth highest average annual police homicide rate for black people, with 32.9 per 1 million black citizens. The Reno Police Department holds the top spot for highest average annual police homicide rate for black people in the country at 71.5 per 1 million black citizens.

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.
