Flower People

My latest visualization is a different aesthetic take on Gapminder data. Specifically this looks at the relationship between the change in life expectancy and income from 1965 to 2015 by country and region. This viz was inspired by Valentina D'Efilippo's amazing Poppy Field visualization. Her work is awesome. Check it out here.

The size of the flower represents current population. The height of the flower represents GDP per capita. And the curvature of the stem represents the change in life expectancy between 1965 and 2015. Click the image to interact.

I also think this visualization is interesting in light of the conversation/debate on Stephen Few's blog regarding the debate between data visualization as an art or science. Few is firmly in the latter camp with others like David McCandless in the former. In my humble opinion there is a time or place for both. This visualization falls more in the art camp obviously. Is it harder to read than perhaps a traditional chart but visually it's more compelling. 

While I don't think a visualization should completely forsake accuracy for art I also think telling a compelling story is part of visualizing data. Ideally, your data visualization should invoke thought or emotion in an honest manner. Now some visual mediums are better for conveying data accurately. And some are more visually compelling and inspiring. Finding that nexus is the fun part of this field.

Zen Master - Thank You!

So the 2015/2106 list of Tableau Zen Masters was announced last week and I was surprised and honored to be on it. It is cool to be named among such awesome company who do such impressive and inspiring work.

Thank you to my Deloitte colleagues (particularly Shine and Julie) and others in the Tableau community for nominating me. And thank you to Tableau for this honor. Sorry my first post immediately after the announcement was the bullet donut chart.

Here is a "360 degree" version of my Zen Master rock built in Tableau of course (image analysis in R)....

Introducing the Bullet Donut

Boom! The bullet donut chart. All the information of a bullet chart with the needless aesthetic of a donut chart. I am pretty sure this is not a thing. So I am claiming I invented it. Why invent it? That I don't know. Behold the stupidity...

I am the first to admit this chart doesn't need to exist. Sorry Stephen Few. It doesn't have the best data-to-ink ratio. And a bullet chart is a much better option. But for those of you out there that like a gauge or a donut chart but struggle to read a bullet chart this might be the chart for you!

Here is a detailed breakdown of what each of the chart elements represent.

Arc Chart in Tableau

Like most people with eyes and a heart I was moved by the gun death visualization by Periscopic. It's powerful and amazingly well done. So using the data from my Supreme Court visualization I attempted to create a similar arc chart in Tableau. This visualization displays tenure by Supreme Court Justice broken out by political party. The height represents the age of the Supreme Court Justice at the time of their appointment (taller = younger) and the color represents the year they were appointed (lighter color = earlier). You can filter to show the change in justice tenure over time.

See details after the break on how to create an arc chart in Tableau.

Tableau Clocks

I recently came across this design project by Swedish artist Humans since 1982 called a million times. These are a series of analog clocks where the hands are used to create various designs including digital clocks. It is an amazing way of applying a conventional image to form a series of new images and designs.

Inspired by this I created a similar visualization in Tableau that achieves a similar, albeit less impressive, effect.
