I think the number one infraction in data visualization is the misuse of color. If I were pressed for time and had to distill my recommendations on color into a Haiku, it would be this: Make everything gray Except the few things you think Should be highlighted Yes, this is simple, bordering on the simplistic, [...]
I hadn’t planned on founding Data Revelations in 2011. It was thrust upon me by a layoff. Out of work, I put a web site together and started blogging about visualizing survey data using Tableau. My hope was that these posts would help me land a consulting gig. As I waited for the phone to [...]
Last week I saw a reprehensible and delusional post from Elon Musk on his social media platform, X. Shortly thereafter I read Robert Reich’s Guardian opinion piece on how Elon Musk has gained a concerning level of power over US national security. For certain, Musk is a genius. He is our era’s Thomas Edison and [...]

I recently participated in a LinkedIn Live discussion about how to visualize uncertainty in survey data with Bob Walker, Anna Foard, and Jon Cohen. I find myself contemplating whether we have a type of moral obligation to try to make sure our audience understands that there may be a big difference between the survey results [...]
Helping your stakeholders see and understand margin of error in survey data. A deep thanks to Anna Foard and Jonathan Drummey for their assistance, Ben Jones for the foundational work behind for my initial explorations, and Ryan Corser for asking me to look into this. Update: an earlier version of this post was titled "Visualizing [...]
I wrote previously about a great bassline that people attribute to James Jamerson, but was performed by then 18-year-old Michael Henderson. Here's another bassline that sounds like Jamerson, but isn't. In 2015 the music world lost Wilton Felder. Most people familiar with Felder know him as a brilliant saxophone player and founding member of the [...]
