However, it is very difficult to find a good way to show the information. In fact, the data contained very little of that. Curiously, the ratings are very dispersed so that each line is graded high on some category and low on others. Here's one view of it:
I have grouped the subway lines together (A/C/E, 4/5/6, etc.). The metrics are plotted left to right in the same order as in the original. Is it all noise and no signal?
(I just realized the vertical axis is reversed: best ratings are at the bottom, worst ratings at the top. Doesn't matter anyway since I can't see any patterns.)

PS. Two contributions from readers. Still looking for insight from this data...
