The image is titled "The Punctuation Continuum" and shows a triangle suggesting an increase in intensity from left to right divided into three sections, each labeled with different types of punctuation marks: "Commas," "Parentheses," and "Dashes." The leftmost section, representing "Commas," is described as "Average, Staid, Almost Invisible." The middle section, representing "Parentheses," is described as "I'm Whispering, Possibly Informal." The rightmost section, representing "Dashes," is described as "OMG! Look at Me!" The credits at the bottom read. "Mignon Fogarty, @GrammarGirl, QuickAndDirtyTips.com."
