How do you make people not just see numbers when looking at a chart, but feel something? This chart of the number of deaths during the Iraq war has always given me a visceral response like no other, and it’s still as powerful as when it was made almost ten years ago. So I made a chart appreciation video to explain what I think is so great about it.

Dots fly across the screen, some of them moving up, some down. They represent black and white boys, and how their income differs from that of their parents and from each other. It’s a great way to show this data in an engaging way and without having to explain percentiles. This is a chart appreciation.

This chart is a staple in every visualization course and many visualization talks. But what does it show, and what does it leave out? There’s a lot more to Napoleon’s Russian Campaign and to Charles Minard’s work than this one chart. My new video looks beyond the surface of what is perhaps the most famous chart out there.

Mechanical calculators are fascinating. I may have gone down a few rabbit holes on this topic earlier this year, and acquired a few. As a little celebration of the end of this year, and to start the new one, I’m creating a small series of videos about them and releasing one each week.

Line charts – they’re not the most glamorous. And yet, they can be used to tell a compelling story about global warming. In this video, I talk about what I consider a modern classic of data journalism, What’s Really Warming the World by Eric Roston and Blacki Migliozzi: how it works, how it’s structured, and why it works so well.

I covered the more commonly known value index charts in my my last video on index charts, this one is about indexing on the horizontal, or time, axis. It’s kind of fascinating how you can fold the time axis to get a better view of your data. I show how it works and walk through a number of examples, using housing prices, camera sales, global warming, and even data about my running!

To show change over time, you typically use a line chart. But when you’re comparing time series whose values are very different, the differences between the lines can obscure the changes within them. Index charts can help with that. They align values to a reference, or fold the time axis on itself, or even do both.

Time to breathe new life into my little YouTube channel, which I’m calling eagereyesTV. I’m doing so with the start of a new series I’m calling Chart Appreciation. Each episode will be on one particular visualization, news piece, or interactive. As the first one, I picked Hannah Fairfield’s Driving Safety, in Fits and Starts from 2012.
