See the IPAW wiki page for discussion.
The dotted lines represent splices, that is, theoretically the objects on each end of a dotted line are the same object appearing in different workload sections. The pass-pass-pass image shows very clearly how the three workload stages splice together. (Note that libc.so and ld.elf_so apparently don't splice together because they can appear in either /lib or /usr/lib, and do so in patterns that confuse the splicer.)
Look at the query text and output. (Probably best viewed together in adjacent browser tabs.)
Note that neither the query language nor the output format is very polished right now.
