This is an incremental post to navigating your family tree from a few months back. This builds off of that visualization technique to manipulate the tree into a radial view. Also, as with the original, the tree is 100% dynamic and you can reset each node in the tree as the root node, toggle between tree views as well as change the API you are analyzing.

Time to Get Hopping with Jump Plot by Chris DeMartini and Tom VanBuskirk

In preparation for the upcoming Think Data Thursday, "I didn't know that was Tablossible", this post introduces a novel graph type referred to as the “Jump Plot”. Jump Plot is the brainchild of Tom VanBuskirk and was first implemented by Chris DeMartini using Tableau. This post is a combined effort from Tom and Chris. There are pieces of this post describing the benefits that Jump Plot provides, however additional details regarding the graph type and all it can offer can be found atjumpplot.com. In short, the Jump Plot provides a new way to visualize event data, with a focus on sequence distributions and bottlenecks.

Fast and Fabulous Custom Maps using Mapbox in Tableau

Fast and Fabulous Custom Maps using Mapbox in Tableau

So the last time I wanted a custom map, I ended up building my own WMS and spending months and $’s to get the map I wanted.  If you followed that advice - good for you. You and I can now drink at at Tableau conference and tell the young’ins about how we used to have to walk uphill in the snow, wearing only flip flops and a Magnum BI t-shirt, while being pelted with popsicles to get our maps. Then one day recently, I had a cocktail with Allan Walker (that insane mapping Zen dude) who pointed out that if you just opened up a .tms file in notepad, there just wasn’t all that much to it but a wee bit of xml.
