New features:

  • GUI: visone console, accessible via the toolbar, replaces the R-console tab and Knime menu/button. Additionally provides a message log. The connection to Knime is now fully operational (cf. their new network mining plugin).
  • GUI: Interaction: The editing mode for manual node and link creation can be accessed by switching the toggle button in the toolbar. Additionally, normal mode now allows zooming to an area by dragging a window with the right mouse-button while holding down the "ctrl"-key.
  • GUI: Default node and link templates have been changed. Default nodes are now round and grey.
  • Attributes: An overview of values for dyad attributes is now available in the attribute manager.
  • Analysis - RSiena: The RSiena interface can now handle missing data and structural ones and zeros.

  • Configuration: The visone configuration folder ".visone" (holding global templates, last used configurations for csv-files, etc.), that was previously saved in the folder from which visone was started, will now be saved in you home folder (Linux) or your Documents folder (Windows). Thus, all instances of visone run on a machine by the same user should share the configurations now.
  • Group nodes: Option to remove all group nodes at once.

Error fixes and other changes:

  • GUI: The "clear background" button was removed from the toolbar. Background information may still be removed via the view menu.
  • Visualization - Mapping: The mappings for node/link label color and size have been moved from the label category to color and size categories.

  • Event-handling was improved for larger networks and visone now has a better handling of situation where memory is insufficient.
  • Save and export operations now warn before overwriting files and the directory last used is memorized. In addition the handling of file name proposals is improved.

Open problem:

  • Group Nodes: are currently not saved to files and can therefore be only used in image exports, we are working on that and will hopefully fix it for the next version.

visone 2.6.3 {#visone_263}

released 2011-02-01

New features:

  • IO / Analysis: New tab R Console provides the possibility to send/receive networks including attributes to/from an R-environment, where these can be manipulated directly. In R, networks are represented by the igraph library.
  • IO / Analysis: Knime connection: Networks may be sent/received to/from a running Knime instance, a powerful visual data mining tool developed at the University Konstanz.
  • IO: Link list import: Networks can now be opened from csv-style link lists. The first two columns in the csv-file must contain node identifiers corresponding to source and target node; additional columns are considered as additional link attributes.
  • IO / Attributes: New attribute type dyad attributes: Dyad attributes provide a way to encode attribute values for each pair of nodes (dyads), mainly used with RSiena. Dyad attributes may be imported and exported from/to csv-files using the attribute manager.
  • Transformation: New network-level transformation “dyad graph” creates a complete graph from the current network displaying all dyads as links and converting all dyad attributes to link attributes of the dyad graph.
  • Visualization - Layout: Added a layout algorithm “stress minimization (dyad attributes)” to represent distances given by dyad attributes.
  • Visualization - Layout: Slight changes in the GUI for dynamic layouts. Added a new layout algorithm “linked layout” that links each node to each of its instances in other networks, and the possibility to calculate and apply an “aggregated layout” to a network collection.
  • Visualization - Geometry: Procrustes analysis: added the option to consecutively perform a procrustes transformation to the previous network in a collection.
  • Visualization: Added an option to apply visualization algorithms to all open networks. Please note that mapping algorithms are applied to networks individually; thus, if a visualization is applied to all open networks, colors, sizes etc. do not share a common scale.
  • GUI: Simplified selection tab.
  • GUI: Option added to save/discard all changes to networks if several networks are closed (i.e., when closing visone or if “close all tabs” / “close other tabs” in the context menu of a network tab is performed).

Error Fixes

  • GUI: Bendpoints of links are now moved with the selection in analysis mode.

visone 2.6.2 {#visone_262}

visone 2.6.1 {#visone_261}

released 2010-06-28

Error fixes:

  • IO: resolved a problem when loading/saving graphs.
  • IO: resolved a problem that caused image exports to be too large.
  • GUI: Templates now incorporate label font and font-size.

visone 2.6 {#visone_26}

released 2010-06-17

New features:

  • GUI: Templates: Added legend functionality. For any node or link templates one may now specify to show them in a draggable legend. Moreover, templates are stored now with each network in the .graphml file (checkbox 'local'), and/or stored globally in visone configurations file (checkbox 'global').
  • GUI: Network collections: Network collections provide the possibility to semantically encapsualte a (sub)set ot the currently opened networks. Currently, this needs to be done for dynamic layouts or RSiena functionality. Network collections are administrated via the network collection manager button in the visone toolbar. Please note that while a network is part of a collection it may not be edited anymore (node/link insertion/deletion).
  • IO: RSiena session files may now be loaded via the open dialog. A network collection is automatically created with a name given by the user.
  • Analysis - RSiena: RSiena integration: Interface for analyzing network collections with RSiena directly from within visone. Options for R-connection have to be properly set in file → options → R - connection.
  • Visualization - Layout: Dynamic layout: Networks in a collection may be laid out together by an dynamic layout approach using anchored stress minimization. The reference network to anchor with may be selected as either one of the collection, a newly created aggregation network, or the previous network in sequence of the collection.
  • Visualization - Geometry: Procrustes analysis: A procrustes transformation can be applied to the networks of a network collection. This operation tries to translate and optionally rotate/dilate a network layout such that it best fits the given reference network.
  • GUI: Animation player: The networks of the currently active network collection may be interactively animated. Accessible via the animation player button in the toolbar.
  • GUI: Zoom: Fit all networks button zooms each open network such that all networks have a common viewport.

Error Fixes:

  • GUI: Undo/Redo: Disabled for now due to unpredictable behavior. We hope to bring a stable Undo/Redo back as soon as possible.

visone 2.5.1 {#visone_251}

released 2009-08-25

New features:

  • Attributes: It is now possible to import edge attributes into the network by an adjacency matrix in csv format, similar to graph import by adjacency matrix. See Attribute Manager → Edges → Export & Import. Row/Column-labels may be used to match rows/columns to the ids of the nodes in the network.

Error Fixes:

  • Visualization - Layout: Centrality Layout now keeps the size of the nodes when applied more than once.
  • Visualizaation - Layout: Status Layout now optionally provides drawing of status niveaus.
  • IO: Background information, i.e., radial/status niveaus are now exported with the graph.

Includes all operations for inspecting, configuring, manipulating, importing and exporting attributes (some of the functionality was previously accessed through the nodes and links menu). Can be started by the button in the toolbar or by the button in the selections tab.
  • Data: Basic support of hierarchical networks: Nodes may be grouped/ungrouped together by right-clicking a selection and applying 'group'/'ungroup'. I/O supported when graphML is used. Nodes may be grouped by attribute values automatically in the transformations tab with the section 'nodes → group by attribute'. Note: Analysis algorithms are applied to the current state of a hierarchical graph, i.e. if a group node is in collapsed state, centralities, for example, will be calculated for the group node and not its children.
  • Transformation: Bibliographic operations in the network section, i.e. squaring the adjacency matrix A, bibliographic coupling (A x A^T) and co-citation (A^T x A).
  • GUI: Number of decimal places in any visual representation of all decimal attribute values in visone may now be configured in the 'File → Options' dialog.

Error Fixes:

  • IO: Fixed a problem with jpeg-export.
  • GUI: Draw multi-links option in the view menu now works properly.
  • GUI: Networks are now properly marked as changed when attributes change.
  • GUI: Resolved several smaller gui problems, like wrong update of overview window.

  • Analysis: added link betweenness and centralities based on link graph. Also the link graph is now available through the transformations tab.
  • Analysis: added clustering algorithms
  • Analysis: added node distances - distance from selected sources to compute the graph theoretic distances from selected nodes. If more than one node is selected the resulting attribute is the minimal distance to one of the selected nodes.
  • Visualization - Layout: added a quick-layout, i.e. MDS and Stress-majorization, available through the quick-layout-button in the toolbar. The quick-layout is applied to all graphs generated with the random graph generators.
  • Visualization - Layout: centrality layout: a radial layout based on attribute values, e.g. centralities; previously called radial visualization
  • Visualization - Layout: added status layout: a Sugiyama-style layered layout where the layering is determined by attribute values

There are also a number of changes to the user interface:

  • new common visualization tab contains all methods from the layout menu, the geometry tab, and the old visualization tab
  • layout: all graph layout algorithms from the layout menu, e.g. random, MDS, stress, link routing, and label placement. Options are initially hidden from the user since most likely there is no need to specify them.
  • mapping: all visualizations of attribute values, e.g. coloring, size, position
  • geometry: translation, rotation, and scaling operations

transformation tab: contains link transformations and link graph

link transformation: the transformations previously found in the links menu, e.g. simplification, merging of edges

link graph: creates a graph with a node for each link. This graph is internally used for some of the link centralities.
