A graphical abstract should be a one-image file and should visualize one overall
process or make a major point clear.
Use a sensible aspect ratio: 4:3, 16:9, or 21:9.
For ease of browsing, the graphical abstract should have a clear start and end,
preferably “reading” from top to bottom or left to right.
Try to reduce distracting and cluttering elements as much as possible.
Font: Times, Arial, or Calibri at a large enough size for display at a reduced size
on a webpage.
File type: PDF or PPTX.
No additional text, outline or synopsis should be included. Any text or label must
be part of the image file.
Do not use unnecessary white space or a heading graphical abstract within
the image file.
