TB Take Two

by Ellen Blackburn

Our challenge for Thursday and Friday was to redo one of our applications to The Data School, by blending it with another data source using Alteryx and creating a new viz on Tableau.

I decided to choose my initial application, which explored the global disease burden of tuberculosis.

When revisiting my application, I immediately noticed several things:

  • It was very long, exploring many (if not all) of the metrics the data set provided.
  • There was a lot of unnecessary/confusing/distracting colours in my graphs.
  • Overall, just too much of everything.
  • Despite 1-3, I was only moderately ashamed.

Accordingly, I endeavoured to make my second viz a lot more simplistic.

I felt my original application had some interesting analysis surrounding case detection rates and mortality, so I thought looking at some more socioeconomic factors surrounding would be interesting perspective to explore. Accordingly, I joined my initial data with used a data set concerning life expectancy and income groups worldwide.  My unskilled attempt at using Alteryx independently can be seen here:

Then I set to work on my viz.

Overall, I’m pretty happy with the outcome. I achieved my overarching aim of simplifying my initial application, yet, I think it still shows some interesting insights when looking at the relationship between the incidence of TB and different income groups.
