What is a "Graphical Table of Contents" Abstract? For one of my accepted papers, the publication editor sent me this note: 


  AUTHOR: Please provide a short “Graphical Table of Contents”
  abstract (maximum 80 words or 3 sentences) summarizing the key
  findings presented in the paper for Table of Content (TOC) entry.


Can someone please explain what that means? I understand the bit about 80 words max abstract but I don't understand why it's tagged "graphical". Is it supposed to be illustrated?
Some publishers (ACS I'm lookin at you) have what they call GToC, which is like a ToC with small images. You might have seen such in some magazines, here's an example.

Accompanying the image is usually a short text that is sort of like a teaser for the article, in a way the coolest tidbit about what you have written. I believe that's what they are asking for here.
