An , log , Line Crossing Algorithm for Levelled Graphsbottleneck for Sugiyama-style layout algorithms. This paper describes an algorithm for leveled graphs, based on the classification of edges that is .(. log .) where . is the number of edges. This improves on the best algorithm in the literature which is .(.. log .). The improved crossing algorithm e

Level Planar Embedding in Linear Time. and . ∈; .. we have . < .. The level planarity testing problem is to decide if G can be drawn in the plane such that for each level .., all . ∈ .. are drawn on the line .. = {(.) | . ∈ ?}, the edges are drawn monotonically with respect to the vertical direction, and no edges intersect except at th

Higres — Visualization System for Clustered Graphs and Graph Algorithmsgres can handle any attributed graphs and perform animated semantic processing of them. The semantics of a graph can be defined by the user in the graph editor. The user can also create new external modules to process graphs with defined semantics. In addition we provide a possibility to extend syst

Partitioning Approach to Visualization of Large Graphscore decomposition as an efficient approach for partitioning large graphs. On the selected subgraphs, computationally more intensive, clustering and blockmodeling can be used to analyze their internal structure. The approach is illustrated by an analysis of Snyder & Kick’s world trade graph.

In this paper we report on the implementation of a clustering algorithm based on the idea of ., a generalization of the idea of the . in graphs. The performance of the clustering algorithm on some large graphs obtained from the archives of Be

Drawing Planar Graphs with Circular Arcspresent a lower bound on the area of drawings in which edges are drawn using exactly one circular arc. We also give an algorithm for drawing .-vertex planar graphs such that the edges are sequences of two continuous circular arcs. The algorithm runs in .(.) time and embeds the graph on the .(.) × .(
