In episode 3 of this mini-series, I discuss the impact of simplified data visualization and how to achieve it. Specifically, I address these factors that affect your visualization:

  • Clutter

  • Mis-alignment
    • Too many visual lines
      • Example misalinged header, legends,
    • Long categories below vertical bar charts not fitting well under the bars (avoid diagonal)
    • How many horizontal and vertical lines (start and stop of visual elements) do you have?
    • Can you avoid a legend?
    • Do you need these gridlines?
    • Do you need tickmarks?
  • Too many elements like
    • Colour
    • Fonts
    • Bold, italic
    • Annotations
    • Header, subheader, sub-subheader
  • “Unnecessary” annotations
    • File names
    • Source data
    • Program name
    • Validation status
  • Understand gestalt principles
    • Proximity - put the description for treatment next to the lines - not in a legend
    • Similarity - re-use color for the lines and the font color of the treatment
    • Enclosure- box around the most important area (e.g. randomized period vs open-label follow up)
    • Continuity - bars being organized below each other have a same starting point - take out the line showing baseline
    • Connection - connect what belongs together - line charts over time
    • Closure - take away the box around your overall vis
