Fishin' in the Mitten: Catching Big Fish in Michigan

Authors: Nolen Akerman

Best Practices
:
  • Well laid out design
  • Excellent story telling
  • Just the right amount of self-exploration and interactivity included
  • Good use of annotations to guide the reader
  • Nice font choice (with two exceptions…see below)
  • Clean design - I like how how removed all of the lines on the chart borders to reduce the noise
  • Good color choices (with one inconsistency…see below)
  • Nice touch to add the fish images
  • Highlighting the major points by making them big and bold (like the years since the record was broken)
  • I like the emphasis on the record in the scatterplot by making it red
  • Nice summary at the top of the records
  • Good use of coloring the months bar chart to double emphasize the frequency
  • Good tooltips, though I would remove the command buttons
Recommended Enhancements:
  • The map bubbles change colors for some reason when you select a different fish. The color does not signify anything that I’m aware of, so a single color should be used for all fish.
  • The text on top of the bars in the bar chart are a different font. This is the only font inconsistency.
  • The font in the scatterplot looks like Arial which doesn’t match the rest of the viz.
  • The decimal places are over-precise. One decimal place would probably be fine.
  • The horizontal bar charts in the middle are set to “fit entire view” which cases the bars to not look so good when there’s only one in the list. I like to ensure all of my bars have the same thickness.

London Cycle Hire Usage

Best Practices
:

  • I’m generally not a big fan of dark backgrounds, but it works well here because it makes the routes stand out.
  • The line width makes the more frequent routes stand out.
  • Good use of filters; they are out of the way as to not distract the reader
  • Simple bar charts that do a great job of summarizing the complex map

Recommended Enhancements:

  • Using a two-colour divergent colour scale might make the route frequency even more evident, but that would be tough with the dark background (contradicting myself, I know)
  • Change the gray fonts to white to make them easier to read

Path to the Draft

Authors: Matt Chambers

Best Practices
:

  • Beautiful design that tells the story without the need for any instructions
  • Terrific background
  • Great fonts and logos that aid in the story
  • Using the official team colors for each team
  • Visually stunning!
  • Tells an amazing story of how 142/200 (71%) of the high school top 100 went undrafted.
  • Fun and engaging; I’m finding a new story every time I click on something.

Recommended Enhancements:

  • I’d like to be able togo backwards this too. For example, I would like to click on an NFL team and see where they got their players from.
  • I don’t care for the default Arial font, but that’s personal preference. I would use something like Helvetica Neue.

Best Practices
:

  • The animation is amazing and startling
  • Great example of storytelling
  • Using the color red is perfect because it represents blood and death
  • Super fast interactivity on mouse-over
  • Really nice bar chart timeline
  • Simple, yet tells a powerful story
  • Proof that vizzes don’t have to be complicated to be impactful
  • Providing a link to additional information
  • Making the data easy to access and download (i.e., transparency)

Recommended Enhancements:

  • Bar chart needs a scale of some sort

Mayweather vs Pacquiao - A Tableau Infographic

Source: Viz of the Day
Authors: Dan Nguyen

Click the image for the interactive version.


Best Practices:
  • Consistent use of colors throughout (though the red for Mayweather farther down doesn’t quite match)
  • I like the long-form infographic style. It makes me feel like I’m reading a newspaper.
  • Great tooltips throughout
  • Nice headers in gold to break up each of the sections
  • The scatterplots do a nice job of showing the differences between the two fighters.
  • Excellent annotations; these make the viz and the analysis completely comprehensible
Recommended Enhancements:
  • Make the red for Mayweather consistent throughout
  • Remove the trend lines on the bar charts; they don’t enough value to justify including them
  • Show the bars as overlapping with one thinner than the other so that they aren’t hiding each other
  • Looks like there’s a bug in Tableau Public that isn’t show Pacquiao’s name at the top
