Slopegraph
Edward Tufte introduced Slopegraphs in his 1983 book The Visual Display of Quantitative Information. He describes them as “compar[ing] changes over time for a list of nouns located on an ordinal or interval scale”.
This example recreates Tufte’s original chart. Getting the labeling correct is a little tricky so it makes a perfect example of something that belongs in a layout.
