This visualization provides an interesting summary of Abraham Lincoln's Second Inaugural Address, based on the words that appear most frequently. Rather than traditional forms of summary such as a paragraph or article, this form of summary allows users to pinpoint which words were most frequently mentioned in Lincoln's speech.

Bad Visualization

While the dataset in this case is certainly quite interesting, the choice of visualization is quite messy and does not express a good summary of information. The choice of a line graph is somewhat confusing, since the x-axis consists of discrete variables, so the graph has no meaning at the lines between data points. Furthermore, the close proximity and similar color of the lines for Iowa and New Hampshire makes it difficult to distinguish between the lines for those two states.
