Data Viz Done Right

#MakeoverMonday: Consumer Spending by Generation

No comments
For week 13, we're making over this viz from Business Insider:


What works well?

  • The generations are sorted from youngest to oldest.
  • The title is clear.
  • The gridlines help guide the eye across the viz.
  • It's easy to compare the general/misc category and the restaurants across generations.
  • A stacked bar chart is easy to understand.

What could be improved?

  • The story in the data, from the article, is about how millennials are spending more on restaurants. It would be good to make that a more obvious focus of the viz. 
  • There are too many colors.
  • While the title is clear, if you don't read the article, you could miss the purpose for the chart.

What I did

I really enjoyed using Google Data Studio last week, so I thought I'd give it another try to continue my learning. Since this was a simple stacked bar chart, I wanted to create a "set" for restaurants vs. all others. I needed to create a calculated field using a case statement that checks the category field. That's it!

From there, it was formatting, which is pretty intuitive as well. I'd highly recommend you give Data Studio a try, especially if you know exactly what you want to build; it's not a data exploration tool.
