For this year’s conference I undertook a project with Keith Helfrich to harvest tweets tagged with #data16. We collected the tweets regularly throughout the week, and updated a view of high level summaries and detailed network visualizations. This post details some of the highs and lows that we came across, and provides access to the workbook so you can do your own analysis and review as well. Please also be sure to check out Keith’s post on the same subject here.Read More
As I embarked on this journey a while back, I had some goals when it came to what I was looking to build. These are summarized in the below bullets.
- Visualize Twitter network growth in detail using some form of network graph
- Needed the network graph for each year to be comparable to one another
- Interactivity against the network graphs was a must
- Provide a way for the user to view the actual tweets
- Once Keith and I decided to run parallel with our efforts, we wanted to way to “jump” from one view to the other.
The sections below detail out how I went about trying to achieve each of these goals. Don’t ask me why I gave myself so many of them.Read More
Note: This is an incremental post to the circular and hive plot network graphing post. When looking back at my network graphing post recently I remembered one piece of the Hive Plot that I wanted to crack and didn't get to in that original effort. One design element that helps distinguish the Hive Plot is the concept of splitting an interconnected axis into two to help visualize this aspect of a network. I think this helps to view the interconnectivity of an axis within the network you are visualizing. Also, with tools like Tableau, we could even allow for an expand/collapse feature on this axis.Read More
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.Read More
We are going to build two tree views in Tableau, an ancestor view and a descendant view of a dynamically selected root person. Within this post I will walk through building the ancestor tree (a binary tree), feel free to reach out if you want more information on how the descendant tree was built, but will leave that to the imagination for now.
First things first, the credits. I started this effort with two main inputs, (1) the node tree link diagram that was explained and created by Jeffery Shaffer and (2) thedynamic parameter posts that Nelson Davis recently went through. I rely on both of these to get to the family tree viz shown here. In addition to these, I also askedAllan Walker, Noah Salvaterra and Anya A’Hearn for general help and guidance along the way.Read More
Recently I posted about creating circular and hive plot network diagrams using Tableau and a question was posted around whether we could also execute theBioFabric network graph within Tableau. There is a lot of additional information about the BioFabric network graph at their website. The super-quick demo is a good intro to the graph if you have not seen it before.
The answer to the question posted is yes and this post is designed to walk you through the steps needed to build your own BioFabric graph within Tableau.Read More
