Converting base 10 frame diagram to base 8 with byte offsets:

Original (https://tools.ietf.org/html/rfc6455#section-5.2):

   This wire format for the data transfer part is described by the ABNF
   [RFC5234] given in detail in this section.  (Note that, unlike in
   other sections of this document, the ABNF in this section is
   operating on groups of bits.  The length of each group of bits is
   indicated in a comment.  When encoded on the wire, the most
   significant bit is the leftmost in the ABNF).  A high-level overview
