Oil Prices Have Plummeted

Source: The Upshot
Author: Neil Irwin

Best Practices:
  • Simple title that tells the story of the chart
  • The aspect ratio of the chart is appropriate (roughly 3x2)
  • Minimalist style: few gridlines, only monthly tick marks
  • Fonts are crisp and easy to read
  • On the scale, only the highest value has the $ symbol included, which helps reduce clutter
  • Footer is muted as to not distract from the viz
  • Final value is clearly labeled and bold, which quickly draws your attention
Recommended Enhancements:
  • It's not immediately clear what time frame the viz represents. I would include the date range in the subtitle.
