Actually, the first one does need the g, should be
mv topo{log,graph}ical.data
It works because it expands to
mv topological.data topographical.data
try it with echo instead of mv to see how it expands. Other uses:
mv myfile.txt{,.tmp} # add extension
mv mymusic.{mp3,mp4} # change extension
mv myarchive.{zip,jar}
