    摘要： A graph layout technique that creates a layered graph layout with a given aspect ratio. The present layered graph layout technique better utilizes the available space and, at the same time, creates an aesthetically pleasing drawing of a directed graph. In one embodiment it determines the layout of the new graph based on a modified Sugiyama technique combined with a modified Coffman-Graham scheduling algorithm. Given a directed graph and a desired aspect ratio, it uses a binary search and the Coffman-Graham scheduling algorithm to find a layout of the graph that has an aspect ratio that matches the given aspect ratio of the available space.
