Has the Snow Finally Stopped?

Source: FiveThirtyEight
Author: Harry Enten


Best Practices:

  • Really interesting design. I love the dot on top of the bar range.
  • Sorting by earliest to latest
  • The legend is really good at explaining how to read the visualisation. This is especially useful when it’s a chart type that isn’t common.
  • Nice clean view; mostly all bits of ink have a purpose
  • Clearly identified the data source
  • Minimal use of color
  • Bold lines to divide the months
  • Nice annotation that explains why two of the cities have their median way at the left end of the range
  • Good subtitle

Recommended Enhancements:

  • The title is misleading. It gives you the impression that winter ends in this range, which simply isn’t true. This is merely when the last snowfall occurred.
  • The gridlines between the months are unnecessary and misleading. This makes it look like there are four weeks in every month when that’s not the case.
  • The months should be spaced by the number of days in each month to make the bar ranges more accurate.
  • Are the horizontal gridlines for each city necessary? I’d have to see the chart without them. They do help connect the city with the bars, but are they unnecessary clutter?
