Data Viz Done Right

Makeover Monday: The Secret of Success

4 comments
For Makeover Monday week 13, we looked at a visualisation that I found on Visual.ly that I use in the Data School's first data viz training class where we look at critically evaluating visualisations.


Andy Cotgreave messaged Eva and me about this particular viz and found a great article that does an excellent in-depth review of this particular piece. Reading the article helped reassure the thoughts that I've had about this chart over the years.

What works well?
  • Engaging design
  • Clear labels on the values
  • Legend matches the shape of each amoeba
  • Everything is scaled in proportion
  • Good color choices
  • Nice big title

What doesn't work well?
  • The subtitle is very offensive. It sure seems this survey was conducted by some extreme right-wing group.
  • The overlapping colors make it hard to follow the pattern.
  • Radar charts are very hard for making comparisons across categories.
  • The radars are curved to make the segments appear to take up more space.
  • Unnecessary icons

I wanted to be able to compare all of the segments in one view, meaning both across social strata and across reasons. I did a quick bit of google image searching to get some ideas for survey visualisations to help gather my thoughts.

In the end, I went with a simple small multiple, waffle chart type design (mind you they are circles instead of squares). I chose to highlight the largest response rate for each social strata and call out in the title the key findings.

  1. Andy, thank you for posting, it is very helpful. I wanted to see if you could post/attach the chart template data source. I downloaded the twbx but since it is packaged, I am unable to see the structure of that datasource and understand how you joined to it. Thank you in advance.

    1. Hi Sam. Here's a bonus tip for you! If you unzip a packaged workbook you'll get all of the data files. Give that a go.

  2. Thank you very much for your reply Andy! I had unzipped the files however when I open the unzipped .twb, it creates a new file location: C:\Users\sam.campos\Desktop\Tableau Downloads\Secret of Success.twb Files\Data\tableau-temp\TEMP_126asaz0kfny1a1c2irck0kk4cbr.tde

    When I go to the data source on the .twb and click "edit data source", I receive this message: Could not find the referenced file 'C:/Users/sam.campos/Desktop/Tableau Downloads/Secret of Success.twb Files/Users/andyk/OneDrive/VizWiz/Waffle Chart Template.tde' Replace with another file?

    It seems to still be pointing to your personal file location?
    If not I apologize, I have not had these problems before, but greatly appreciate your help. This viz is what our team has been looking for and would be perfect. Thank you so much Andy!
