### Import

- AdjacencyMatrixImport

  Description

  This plugin enables to import a graph coded with a matrix

  File format:

  The input format of this plugin is an ascii file where each line represents a row of the matrix. In each row, cells must be separated by a space.

  Let M(i,j) be a cell of the matrix :

  - if i==j we define the value of a node.

  - if i!=j we define a directed edge between node[i] and node[j]

  If M(i,j) is real value (0, .0, -1, -1.0), it is stored in the viewMetric property of the graph.
  If M(i,j) is a string, it is stored in the viewLabel property of the graph.
  Use & to set the viewMetric and viewLabel properties of a node or edge in the same time. If M(i,j) == @ an edge will be created without value
  If M(i,j) == # no edge will be created between node[i] and node[j]

  EXEMPLE 1 :
  A
  # B
  # # C
  Define a graph with 3 nodes (with labels A B C) and without edge.

  EXEMPLE 2 :
  A
  @ B
  @ @ C
  Define a simple complete graph with 3 nodes (with labels A B C) and no label (or value) on its edges

  EXEMPLE 3 :
  A # E & 5
  @ B
  # @ C
  Define a graph with 3 nodes and 3 edges, the edge between A and C is named E and has the value 5

  Bubble Tree Drawing Algorithm :
  D. Auber and S. Grivet and J-P Domenger and Guy Melancon,
  In International Conference on Computer Vision and Graphics, pages 633-641, september 2004.

  HISTORY

  - 07/12/04 Version 0.0.3: Use new Tulip plugin parameter mechanism

  - 16/07/03 Version 0.0.2: Better management of node size

  - 16/05/03 Version 0.0.1: Initial release

  NOTES

    This algorithm only works on trees. Let n be the number of nodes, the algorithm complexity is in O(n) or O(nlog(n)), By default O(nlog(n)) algorithm is used, but one can choose the complexity by using the argument (bool)"complexity" (true means O(nlog(n), false O(n)). The algorithm can manage nodes of different size. The SizeProperty "viewSize" is used by default if no parameters are given to the plug-in. The parameter is (SizeProperty*) "node size".

- GEMLayout

  Description

  An implementation of a spring-embedder layout.

  This plugin is an implementation of the GEM-2d layout algorithm first published as:

  A. Frick, A. Ludwig, and H. Mehldau,
  "A fast, adaptive layout algorithm for undirected graphs",
  In R. Tamassia and I. Tollis (Eds),
  Graph Drawing'94,
  Volume 894 of Lecture Notes in Computer Science, Springer Verlag, 1995.

  HISTORY

  The implementation started life as the public-domain code produced by Arne Frick and released at

  www.frick-consulting.de/publications.html

  The core "embedder" part of the algorithm was used in the implementation of a Java plugin for the CWI "Royere" tool, and then this code was ported to C++ to make the implementation given here.

  NOTES

    The embedder algorithm described by Frick involves three phases: insertion, arrangement, and optimization. Only the first two of these phases are included here. Experiments with the Java implementation showed that the optimization phase consumed significantly more time than the first two and produced apparently marginal improvements in the final layout.
    As GEM, like other spring-embedder algorithms, is computationally expensive, I have tried to optimize the loops somewhat by storing all necessary node information into two arrays: "GemProp" carries the (scalar) values associated with each node by the layout algorithm, while "Adjacent" is an array of vectors, one vector per node, giving the index (integer) of each node.

    The new version has been reimplemented to manage edge length it merges the 3D stuff and removes the use of integers (new CPU do not require it anymore).

- MixedModel

  Description

  This plugin is an implementation of the planar polyline graph drawing algorithm, the mixed model algorithm, first published as:

  C. Gutwenger and P. Mutzel,
  "Planar Polyline Drawings with Good Angular Resolution",
  "Lecture Notes In Computer Science, Vol. 1547"
  "Proceedings of the 6th International Symposium on Graph Drawing,"
  pages "167--182"
  1998

  Let n be the number of nodes, the original algorithm complexity is in O(n).
  But the implementation of the canonical ordering has not been made in O(n).
  This version of the algorithm considers each connected component of the graph, tests if it is planar or not. If not, it computes a planar subgraphs, which is a maximal planar "sub-map". Then an area aware version of Gutwenger and Mutzel 's algorithm is used, and if the connected component was not planar, it adds the "unplanar" edges in 3D. Finally, it uses the Connected Component Packing plugin of Tulip Software to pack the connected components.

  Description

  An implementation of a simple tree layout.

  This plugin is an implementation of a simple tree layout. All leaves are placed at a distance one (x-coordinates) and the order is the one of a suffix ordering. The y coordinates is the depth in the tree. The other nodes are placed at the center of their children (x-coordinates), and the y-coordinate is their depth in the tree.

  HISTORY

  - 01/12/99 Verson 0.0.1: Initial release

  NOTES

    Let n be the number of nodes, the algorithm complexity is in O(n).

  Description

  This plugins compute for each node n, the maximum path-length between n and the other node. The graph must be acyclic.

  NOTES

    This algorithm works on general graphs.

- EccentricityMetric

  Description

  This plugin compute the eccentricity/closeness centrality of each node

  Eccentricity is the maximum distance to go from a node to all others. In this version the Eccentricity value can be normalized (1 means that a node is one of the most eccentric in the network, 0 means that a node is on the centers of the network).

  More information about the use of eccentricity metric can be found in :

  Visone: Analysis and visualization of social networks.
  "Book. Graph Drawing Software. (Ed. Michael Junger & Petra Mutzel",
  Authors : Ulrik Brandes and Dorothea Wagner.
  "2004",
  pages 321-340.

  Closeness Centrality is the mean of shortest-paths lengths from a node to others. The normalized values are computed using the reciprocal of the sum of these distances (see "http://en.wikipedia.org/wiki/Closeness_(graph_theory)#Closeness_centrality" for more details).

  NOTES

    The complexity of the algorithm is O(|V| * |E|) time and O(1) space.
