## graph-boundaries

Arguments: nodes center-x-reader center-y-reader width-reader height-reader

This utility function might be useful when using the function graph-layout to draw graphs and handle mouse events on them. The arguments should be the same as the same-named arguments to graph-layout. See that function for more information.

This function returns values that indicate the extent of all of the nodes in a graph. Four values are returned, which are real numbers. They indicate the left, top, right, and bottom sides of a rectangular region that encompasses all of the nodes in the graph. The units are whatever arbitrary units are returned by the reader functions that are passed as arguments to this function.
