Edward Tufte forum: Slopegraphs for comparing gradients: Slopegraph theory and practice

write a program posted on github or as a Chrome app whose output closely replicates the (1) GNP slopegraph and the (2) cancer survival slopegraph immediately below. Necessary subtleties include thin gray lines that don’t crash into words/numbers, typeface Gill Sans or equally refined, tuned ordinal spacing of words at left the
line paths, probably best to make each line graph separately and then order and stack them appropriately to avoid too many line crashes. The idea is to compare slopes, with what are in effect a set of separate plots then ordered by first entry and then stacked with
some optical care.
