Assignment

Distracting asterisks after titles
The text formatting isn't consistent througout 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 unnecessary use of arrows instead of simple bars, which don't offer any additional information
The vertical scale isn't equal on both bar charts 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 for the bar representing Hoover's return value making it difficult to read
The data ink ratio is very low due to unnecessary gradients, lines and redundant information

The subtitles are just continuations of the titles instead of offering an additional (or 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 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 faciliate fast horizontal scanning
The vertical text has been placed horizontally beneath the respective bar to increase it's readability

The "subtitles" have been aggregated into 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 have been reduced to years to remove irrelevant information
