I'm looking for a way to use drag-and-dropping to pick up a graphic
and move it from one place to another. For example, I thought I could
get my feet wet by writing a script to represent small graphs (in the
nodes-and-vertices sense) as collections of dots and lines onscreen.
Moving the the dots around (while maintaining line-indicated
connections between dots) could furnish a graphical way of
investigating questions like planarity and isomorphism.
