Hmmm, the Y axis of the graph is tough to interpret. Isn't it kind of weird to use a percentage for a line graph? With percentages, the goal is to provide an obvious fractional breakdown, that viewers can readily sum to 100%, visually. I have no idea how to sum a curve and reconcile back to the original universe. If the complete set of links in this data is a count of 12,373 links, then how many have decayed? Based on that graph, I have no idea.
