Perhaps one of the greatest things about Tableau is how industry-agnostic it is. Though some industries are predisposed to be more data-driven than others, Tableau is making it criminally easy for anyone in any vertical to get more from their data. As a leading Tableau...
In 2016, the U.S. had an historic presidential race between Donald Trump and Hillary Clinton, the first woman to run for U.S. president. While we’re still waiting on a female president in the U.S., the race led me to wonder about women in other areas...
This morning, while reading my RSS feeds, there was an interesting map showing Netflix streaming activity by state published by HSI. The visual didn’t make it easy to see the most popular show incidence. In a few minutes, I created this view in Tableau that does: ...
The idea behind these reports is to allow the user to explore Medicare Part D Prescription claims across the country. In 2014, Medicare Part D had 40.5 million beneficiaries. That’s roughly 12 out of every 100 Americans, which equates to a lot of data. In order to...
Ah, the weeks after Thanksgiving. Nothing but cold turkey sandwiches and residual guilt from eating so much. Even though this post comes at a time when we're all exceedingly tired of this tasty fowl, I couldn't get an idea for a viz out of my head: Why...
Washington, D.C.’s Metrorail, opened in 1976, covers 110 miles of subway track, 6 metro lines and 91 stations. System upgrades have been long overdue, with considerable malfunctions and delays surfacing at greater frequencies over the past few years. From a train fire that killed a passenger to...
Tableau Conference 2016 is rapidly approaching, and data visualization aficionados from around the world will descend upon Austin. While the expo hall will be a great place to explore the Tableau community (be sure to visit InterWorks at booth #107) and events like Data Night...
As a roving consultant, I’ve always been fascinated by the different paths that people take to get where they’re going. More often than not, they twist and turn in the most unexpected of ways. With TC16 just around the corner, I have the unique opportunity...
According to www.theknot.com, the average wedding in the United States costs approximately $30,000. With about two million weddings a year, this results in a multi-billion dollar industry. Every time someone says yes, plans must be made. Whether you are getting married at a courthouse, your...
In the first post of this series, we reviewed how you can calculate compound annual growth rates in Tableau. This week, we’ll look at time series data using Bollinger Bands. A technical stock analyst named John Bollinger developed the technique and trademarked the name. Bollinger bands simply...
Every decade, I spend a few weeks planning the next 10 years. This thinking normally encompasses career and investment goals. This time, I decided to expand my time horizon. I’m 57 years old, so I wanted to start thinking about what my personal financial situation looks...
The City of San Francisco's Health Department is always busy making sure our local restaurants are meeting food safety standards. Thanks to SF Open Data, scores and violations for every restaurant are available to anyone. Naturally, I wanted to take this data and give it life...
Jump to the viz! August in America brings record temperatures and signals an end of six painful months without American Football. Sports news websites begin to surge in traffic; even ESPN, despite their broad coverage of global sports, gains significant ground in its Alexa rankings once...
With nearly three years under my belt as a resident of New York, I’m still a relatively fresh newcomer to the city. And while I love this city and could talk your ear off about the many reasons why, I’ll admit that there are plenty...
.mw { max-width: 90%; } Divvy Bikes, Chicago’s fantastic and vast bike sharing program, gives both local commuters and tourists alike an alternative option to Public Transit or taking a cab. My goal for this dashboard was to create a comprehensive guide to get to know your neighborhood Divvy....
With the non-stop talk around NYC about “Hamilton,” I figured it’s about time to look into some Broadway data. As someone who is not well versed in the theater community as a whole, it’s been interesting to see many people (myself included) become so enamored by...
Today, I got a really interesting request to create a Venn diagram in Tableau that showed the overlap in customer segments. I had seen the 3 Way Venn done by Rob Austin here at InterWorks; however, I needed something that allowed me to select the intersections...
