Description of the third exercise (German)

The Original Charts[edit]

Critique of the Given Charts[edit]

Visual Design[edit]
  • Distracting asterisks after titles
  • The text formatting isn't consistent throughout the document (with and without serifs, capital letters for subtitles, slanted text, etc.)
  • The needless use of a bubble chart for data, which could be communicated more efficiently with a bar chart
  • The use of arrows instead of simple bars doesn't offer any additional information
  • The vertical scales on both bar charts aren't equal in favor for the democrats. The bar charts are therefore not comparable.
  • Percentage values, president names and election periods aren't aligned in a line causing difficulties regarding fast horizontal scanning
  • The use of vertically aligned text regarding the bar representing Hoover's return value is making it difficult to read
  • The data ink ratio is very low due to unnecessary gradients, lines and redundant information
Content[edit]
  • The subtitles are just continuations of the titles instead of offering an additional (or rather alternate) explanation
  • The bars could be aligned in a time series for an additional quality of information (e.g. depressions, regressions, etc.)
  • The exact dates of the election period of each president are irrelevant information

The Revised Charts[edit]

Description of the Undertaken Improvements[edit]

Visual Design[edit]
  • The titles have been capitalized following the rules for any title
  • Special considerations have been made regarding the consistency of text formatting to enable fast processing of information
  • Text formatting varies according to the degree of importance (e.g. bold percentage values, light gray text color for dates, etc.)
  • Light gray guides and a ruler have been plotted to ease the comparison of the bars over a greater distance
  • The bubble chart has been replaced with a more sophisticated bar chart to increase comparability and to avoid visual clutter
  • Bars have been used instead of arrows to increase the data ink ratio and to avoid visual clutter
  • Percentage values, president names and election periods have been aligned in a line to facilitate fast horizontal scanning
  • The vertical text has been placed horizontally beneath the respective bar to increase it's readability
Content[edit]
  • The "subtitles" have been joined with the titles
  • The bars have been aligned in a time series for an additional quality of information, inherently undermining the problem regarding the unequal vertical scales
  • The display of the election period dates of each president has been reduced to years to remove irrelevant information
