Originally introduced to the Tableau Public API by Tableau Enthusiast, Rodrigo Calloni, I couldn’t wait to assemble a whole list of people so that I could start to compare stats and spot trends. I’ve been assisted by numerous people in the community as I worked through the data, and a special thanks to Amar Donthala who helped me get started with this Alteryx workflow.
So there was a great FiveThirtyEight visualization this week that had a county-level sequential map showing disease related deaths. Their map had AK and HI so it reminded me that I still wasn’t satisfied with any of my current solutions in Tableau. In doing a little research, I found that was referred to as the Albers US Projection.
We were talking about Square Charts (aka waffle charts) recently at work, and I had just created an Excel template for my Data Visualization class. While Russell Christopher had a great post here I like it when the value is a perfect square, for it to show a solid square at the bottom right. If you watch through my moving GIF, you will see what I mean.
This week one of my students asked me how to recreate the ascii style pig found in Russell Spangler’s ‘Whatcha Know About Bacon’ viz. My initial reaction was that deconstructing Spangler vizzes usually hurts my brain, yet as an old school gammer, ascii text seemed within my grasp. It turns out that I figured it out (with some help) and have made it easy for anyone to replicate in less than 5 MINUTES!
For my class at Temple I was looking for some good local data to teach people about maps & Tableau Mapbox integration. So I came across the site PennFoodTrucks.com and they provided me with a full download of their data files for a unique little data set!
It doesn’t matter if you were preparing some images for a Tableau viz, or working on your presentation for #Data16, here are some really easy techniques to up your game (quickly and without fancy software).
Set Transparent Color – This is the fastest way to make a solid background transparent, but this example shows you why this is far from perfect when you have shadows and gradients.
Since seeing the work that Ancestry.com is doing with wrapping Tableau in a bootstrap portal, I loved the idea but haven’t had the time to build (or more accurately have my team build) the framework to support it. I also interact with over 100 site owners of varying skill levels, and not everyone is looking to support a portal solution outside of the Tableau server.
So I’ve turned to Robert Rouse’s slide out Menu Container in order to achieve the same effect. While I’m not a big fan of supporting custom tricks, once this solution is implemented, it isn’t hard for others to modify and support.
This is my attempt to practice this technique and make a template example that could be reused for simple dashboards.
Recently on Twitter, local Philly viz enthusiast @ asked if we could use @‘s Hex map technique to move the states around to get Alaska and Hawaii on a single map so that we don’t have to float elements. This is a particularly useful idea if we are thinking about a scenario where we swap between map types (standard, tile, hex). This is ultimately a blog post about several failures and a partial success. But failing is amusing… so read on for your own amusement.
