Here you’ll find tips and tricks for #dataviz and examples of data visualization.
Tableau 2018.1 introduces a lot of new features, especially geospatial features that open a whole new world of data exploration and analysis. With support for SQL Server geospatial data types, there are near-infinite possibilities. I’m sure I’ll have more than a few posts on various options soon! Here’s one thing you can do: render circles […]Continue Reading... 11 Comments.
I love hex maps! Especially for the United States, you can keep states in a basic geographic orientation, but eliminate the visual perception problems caused by the fact that some states are huge compared to others (and Alaska and Hawaii shift the scale when added). But there are a few headaches that can occur when […]Continue Reading... 18 Comments.
I used to think you couldn’t hot-swap geographic levels of detail in a Tableau visualization. And, before Tableau 10, you couldn’t. I mean, of course in Desktop or web authoring mode you can drag and drop fields, but for the end-user of a dashboard that wasn’t an option. You might have thought to use […]Continue Reading...

I recently competed in the Tableau Iron Viz where Tristian Guillevin, Jacob Olsufka and I raced to build a dashboard in 20 minutes! One of the most incredible things about Tableau is how versatile it is as a tool. You can spend hours to build a stunning Tableau dashboard or just a few minutes to […]Continue Reading... 10 Comments.
I was part of a conversation recently where something like this was said: “We need a data model that will bring all of our data together so that we can analyze risk and do predictive analytics… No, just build the model, don’t worry about using Tableau – we’ll do that after you build the model […]Continue Reading...

Wow! I’m still stunned to have won the first IronViz feeder contest for 2017! And excited! And humbled. And honored. Wow! Thank you to everyone who has had kind words of encouragement! You can read some broad description of my entry here: The Changing Shape of History: From the Colonies to the United States. In […]Continue Reading... No Comments.
I previously shared the fun I had with Tableau 10.2’s ability to connect to spatial files. In that case, I used historic shape files from the Newberry Library’ repository of historical county boundaries files. When I saw that the first Iron Viz feeder contest would feature spatial file visualization, I knew I already had an interesting data […]Continue Reading... 1 Comment.
Recently, I gave a presentation on storytelling with data visualization. I described the elements of a story, how to leverage the power of telling stories, and how to avoid dangers of data storytelling. Here is the story I shared:Continue Reading... 2 Comments.
Stories are powerful. They connect an audience with people, facts, emotions and action. They help us understand difficult concepts and relationships. They help us make connections between things we wouldn’t otherwise. And we remember stories far better than we remember raw facts. Quick: list the last five vice presidents of the United States. Now tell […]Continue Reading... 1 Comment.
Tableau 10.2 is almost here! And it’s time to celebrate! One thing I’ve always wanted to do in Tableau is create interactive historical maps that changed based on the selected time-frame. We are fairly familiar with the shape of things now – countries, states, counties – but how did things look in the past? What […]Continue Reading...
