A low-resolution photograph of an individual, usually taken from a distance at maximum zoom with an iPhone camera, and then zoomed in further. The end result is a Sawadagraph that vaguely resembles the subject, enough to be recognized by an acquaintance but not a stranger.
A Sawadagraph is usually taken when one wants to discreetly take a picture, but does not want to get caught. It also is a simple graph with a pendant vertex at the top in terms of graph theory.
