A World of Languages in One Visualization

Published

on

One of the most exquisite and elegantly designed visualizations I have encountered is this chart by designer Alberto Lucas López titled “A world of languages”, which explores the incredible diversity of languages spoken around the world. The thoughtfully chosen colors, spherical format, organic yet minimalist layout, and simple elegance make for a pleasing graphic worthy of being framed on the wall.

Did you know that there are at least 7,102 known languages that are alive in the world today? 23 of these languages serve as the primary form of communication for 4.1 billion people! The colors provide insight into the regions where the languages originate, which helps give a sense of the population, history, and power of these dialects. There are additional charts below the main feature that showcase the most popular languages being learned around the world, the number of countries in which the most prominent languages are spoken, and the distribution of living languages by country. It may come as no surprise that English is the most popular language to learn with 1,500 million learners!

This graphic also highlights the incredible linguistic diversity of Papua New Guinea. According to the chart, 839 languages are spoken in Papua New Guinea. Why is Papa New Guinea such a linguistic mosaic? There are many elements to Papua New Guinea’s abundance of languages, but one of the most fascinating factors is how the rugged landscape (with mountains, jungles, and swaps) keeps tribes isolated, which preserves their languages.

Real Estate Chart Reveals Your Money Has Only 50-80% of the Buying Power it Did 5 Years Ago

Published

Houses aren’t cheap these days. In fact, they are so not cheap that millions of young Americans are holding off on buying a home and are instead opting to rent for the foreseeable future. “Just how bad is it?”, you might be wondering. Well, this new visualization from construction app maker Builder Pad forces you to look at the problems the United States is facing in the real estate market in an entirely new way. From this perspective, you are able to see how much smaller a house you’ll be able to afford today vs. 2018 for the same amount of money. So, how much smaller has a $500,000 home become in your state?

In order to reveal which states have the fastest-rising real estate prices, Builder Pad analyzed median listing prices by state in two distinct ways. First, is by percentage of square feet lost over the five year period between 2018 and 2023. The state that was hit the hardest in this metric is Montana where a $500K house is now 50.15% smaller. Just typing that out blows my mind.

The second metric used in this study is square feet lost over the same 5-year period. The state that lost the most square feet in a $500,000 house is Kansas with a drop of 2,280.26 square feet. That’s the equivalent of losing five (5!) two-car garages in living space. With virtually no end in sight for this real estate conundrum, what will be the straw that breaks the camel’s back?

56 Military, Commercial, and Personal Aircraft Ranked by Top Speed

Published

What can go nearly six times the speed of sound and cost $2.5 trillion dollars to build and operate (adjusted for inflation)? The answer is the North American X-15, hypersonic rocket-powered aircraft that achieved the fastest aircraft flying speed of all time on October 3rd, 1967 when it reached 4,520 miles per hour! That is an awe-inspiring 75 miles per minute and 1.25 miles per second. GlobalAir.com has launched a compelling (or propelling?) chart visualizing aircraft ranked by max flying speed. More than half of the aircraft shown are capable of flying faster than the sound of speed!

How fast is the sound of speed anyway? Mach 1, or the speed of sound, varies depending on the temperature of the air (or other medium) that it is passing through. So at sea level on planet Earth at around 60 degrees Fahrenheit, the speed of sound is approximately 767 miles per hour. That means that the North American X-15, an aircraft operated by the United States Air Force and the National Aeronautics and Space Administration, flew at a rate nearly six times as fast as the speed of sound. The record was achieved by William J. Knight, a Vietnam combat pilot and test pilot for the U.S. Air Force. During his 16 flights in the aircraft, Knight became one of the few non-NASA pilots to earn their Astronaut Wings by flying an airplane in space – this was achieved by reaching an altitude of 280,500 feet (53.125 miles). It truly is extraordinary how far aviation technology has come in a century!
