I first saw this survey in print at Gatwick airport on my way to Prague, then it appeared in feedly. I know from speaking to John Burn-Murdoch that the print and online graphics standards are different. The print version I actually found easier to understand because it used blue for negative sentiment.
What works well?
- Clear sorting by very satisfied
- Sticks to their color guidelines
- Simple title
What could be done differently?
- Use different colours for the negative and positive sentiment
- Add an overall score (like net promoter score)
- Include 2012 for comparison so that you can see which of these cities improved
- Add a more descriptive title so it's even more clear what the audience is looking at
I used a few resources to help me create my final visualisation:
- Steve Wexler's post about Likert scales and Net Promoter Scores
- This Github page that has the official FT colors
- This knowledge base article for including barcharts in tooltips
First, I recreated the FT viz, but with different colors for negative and positive sentiment. I also included bar charts in the tooltips.
Next, I included 2012 and labeled the bars where they fit.
I don't particularly like the labels on the bars, so I've removed them from the final version. I also changed the bars to a Likert scale, which moves the negative to the left and positive to the right, and helps shows the discrepancy better. I also included the net promoter score.
Last, I added a slope graph to help show the change and included a more descriptive title and subtitle. You can click on any bar and it'll highlight in both places.
