This is a Parallel Coordinate Graph. A parallel coordinate graph is used for multivariate data sets. Admittedly, I am not sure what anyone could get out of such a graph. I searched in order to find some sort of "best practices" usage for this type of graph but could not find one. My best guess is that this graph would be useful in determining similarities of patterns among variables within a multivariate set. Perhaps, much like looking at the graph seems to be, it is more literally a "needle in the haystack" syndrome in finding the variables that "clump" together and thus grab the viewer's attention the most.
