The article "This missile could reach California. But Can North Korea use it with a nuclear weapon?" from 2017 uses visualizations and diagrams of missiles and their reach: https://www.nytimes.com/interactive/2017/08/22/world/asia/north-korea-nuclear-weapons.html
The first thing that came to my mind while reading this piece: It is very clean and smart in its design and its content. All the visualizations the NYT uses refer to the main question in the headline. The visualizations are simple and plain which make them - in my opinion - more appealing to look at as the topic itself is very technical.
