What do the arrows mean?

I can sort of understand an arrow from dba_tables, dba_indexes and dba_clusters to dba_segments. Clusters, tables and indexes are all segments, so that makes sense.
But an arrow from dba_tablespaces?

Conversely, dba_tab_histograms is sitting linked to nothing at all, though one might have expected an arrow from dba_tables or perhaps from dba_tab_columns.

I can't work it out.

And what's the significance of the white, light blue and grey/purple colour codes for the various views? I thought light blue meant 'new in 10g' at one point, but that can't be right, since DBA_TABLESPACE_GROUPS is certainly light blue, but so is DBA_FREE_SPACE, which isn't new at all.
