Fascinating Interactive Visualizations of Data

Maybe I'm a visual data wonk. I fell in love with Gapminder years ago.  Today I discovered Insightful Interaction, which displays a wide array of data in visually illuminating ways.  Scroll down, click on any title that intrigues you, read the key info provided, then use your cursor to explore.  I found lots of data that surprised me, such as:

• 200 years of immigration to the US (1820-2015)
• The top 15 defense budgets in the world
• Rural hospital closures in the US: 2005-2016
• A world map of unmatched 25-45 year-old singles

Way cool, yes?  I had fun thinking about how I might use this with middle and high school students. I'd welcome your ideas on this.
