Following on from my post about where to play blackjack, here’s a basic strategy tester and strategy table built in Tableau. The idea is that if you play perfect strategy, you minimize the house advantage and your losses. By playing “with your gut”, you’re giving the house a massive advantage, especially if you’re not doubling …

Where to Play Blackjack in Vegas
With the Tableau customer conference fast approaching I thought a blackjack visualization was appropriate. If you play blackjack using basic strategy (hitting, standing, doubling, etc. depending on the cards showing) you can minimize your losses over time. However, short of card counting or cheating, the house always has the advantage, although slight – typically in …
Beer and Calories and Alcohol and Calories Per Alcohol and…
How many calories do you save by drinking light beer? Or perhaps the better question, if the alcohol content is lower in light beers, how many calories am I saving to get as drunk? This visualization answers that and more. The data is from Beer100.com and I’ve added lots of sort, coloring, highlight and filter …
Book Review: Rapid Graphs with Tableau Software
Even though Tableau has been round for a number of years now, there is a dearth of books out there to guide new users. To get the most out of Tableau, you don’t want to approach chart making in the same way that you do in Excel. The videos and webinars that Tableau offers are great, …
Slopegraphs in Tableau

They are highly effective because you have both the text (the reader would likely want to know the individual values), the sorting, and the slope which allows you to understand the …

Exploring Data in a Single Chart
Chandoo’s excellent Excel and Data blog has a data challenge to win a Kindle. I’m not entering but thought I’d show what Tableau can do with just a few hours of work. The challenge was to create a single chart that showed the data story the best. Below is what I think works, but the …
The US has 3 years of Oil in the ground: Oil exports, imports, and consumption
Many people are unaware of the massive amount of oil and refined petroleum that is shipped and consumed around the word. Every day, there are approximately 84 million barrels of oil used. Every day. 3.5 billion gallons, 5345 Olympic swimming pools, 13 Empire State Buildings. Quite unbelievable. To understand who is using the oil, where it’s coming from, and …
Unemployment Rates 1982 to 2011: Dorling Cartogram
I’ve updated the Dorling Cartogram on unemployment rates by state to include 2010 and data from April of 2011. As you can see the massive explosion of unemployment rate in 2009 has tempered slightly since then. The data is from the Bureau of Labor Statistics, and rendered using Protovis. As before, you’ll need an SVG …

I find this… pleasing. Edit: Richard Leeke made a Tableau version (see comments below). Tableau Public doesn’t animate it automatically, so download the workbook to see the effect best. Wave Pendulum Powered by Tableau
