Gephi 0.8 beta released

The latest beta version of Gephi has been released, download it for Windows, Mac OS and Linux platforms. This release focus on new features for both users and developers, and the new license unlocks opportunities for business. The Ranking and Preview modules have been completely rewritten in a modular way and can be now extended with plug-ins! Preview can now be extended in many ways, for instance group shapes or edge bundling. Moreover, continuous progress have been made on the dynamic network support and we release today the last big part: statistics over time, available from the Statistics module when the network is dynamic. Thanks to users who reported bugs, it’s the only way to fix them.

The team will now start developing the 0.9 version of Gephi (please consider joining us!) and integrate the latest Google Summer of Code projects, including a new timeline. We are also willing to help as much as possible plug-ins developers to get things done and improve documentation. We want to leverage the new Preview and will help newcomers to get started.

Because it’s a major release, changes are not deployed through the AutoUpdate, you need to download and install the new version. Plug-ins also need to be checked for compatibility. They will reappear on the Plugin Center in the coming days, as they are verified. Thanks for your patience.

Consult the release notes and the new Javadoc for more information.

Features highlight

Ranking Auto Apply Dynamic Ranking

Ranking now works with dynamic networks and it’s easy! When manipulating a dynamic network with the Timeline simply enable the ‘Auto Apply’ and the color/size is updated in real-time. To import a dynamic node size simply import a regular dynamic column in your GEXF and select it in Ranking like before.

PNG Export PNG Export

A new powerful PNG export has been added to the existing PDF and SVG export. One can create high-resolution network images with all the customization available in Preview. You can even create transparent background images!

New Preview New Preview

Major effort to completely rewrite the Preview module in a modular way. One can now create plug-ins for Preview! The new Preview includes new opacity options, a text outline, radius (customize edge start/end points) and a simplified list of properties.

Dynamic Metrics Dynamic Metrics

New dynamic metrics in the Statistics module: Dynamic Degree, Dynamic Node Count, Dynamic Edge Count and Dynamic Clustering Coefficient. Dynamic metrics are executed on a dynamic network and allow to analyze how network properties evolve over time.

Gephi 0.7beta released

Major milestone for Gephi today. The 0.7 beta version is ready for download for Windows, Mac OS and Linux platforms. It brings many awaited features and more than 80 bug fixes!. Stability and productivity improvements are the main objectives of this release. A complete support for longitudinal network is part of this release, it is now more easy and flexible to import and explore dynamic networks. Consult this new tutorial to see how input longitudinal networks in Gephi. We support three different methods, to cover all use cases.

Because it’s a major release, changes are not deployed through the AutoUpdate, you need to download and install the new version if you had the alpha. Plug-ins also need to be checked for compatibility. They will reappear on the Plugin Center in the coming days, as they are verified.

Consult the release notes and the new Javadoc for more informations.

An announcement for modules developed this summer by the Google Summer of Code students, in particular Neo4j and Social Network import. They may be fully integrated in Gephi for its 0.8 version, in the meantime they will be released as plug-ins through our Plugin Center. Stay tuned, it will be fast.

A new version of the Gephi Toolkit will be released in a few days, based on the beta codebase.

Features highlight

New Data Laboratory

The Data Laboratory receives tons of new features, developed this summer by Eduardo Ramos. It now proposes to manipulate and edit data in a broader and more productive way. A detailed list of features is available on the Introducing Data Laboratory post. The laboratory is also now auto-refreshing when filters are manipulated. Another essential point is that the laboratory is easily extensible with plug-ins.

Longitudinal networks

They are now fully supported in Gephi. Explore how the network topology change over time by using the Timeline component, which now appears automatically. The major improvement is the dynamic attributes support. The edge weight or any attribute value can evolve over time as well, and the visualization shows the value in the right range. Enable the timeline with a single button. See tutorial.

Edit

Simple edit by selecting one or several nodes or edges in the Data Laboratory. Keep Control key on the table to select several rows and change values of several elements in one action. Edit also manually visualization variables like color, size or position. The Edit window is available by right-clicking on rows. Many other features are now available through the context menu, and more can be added with plug-ins.

Search/Replace

General Data Laboratory actions like Add node/edge, Search/Replace or Import CSV. The Search/Replace feature shows an advanced UI to search and replace values in the table cells. It can do a normal search or a regular expression based search, among other useful options. It is implemented in a separate controller that is part of the Data Laboratory API.

Columns merge

Manipulate columns and do basic calculations. On numerical columns one can get sum, average, median, … from several other columns. New columns can be created from a regular expression based on a existing column. Among other merge strategies, a Time Interval column can be get from a simple numerical column. Get a longitudinal network from a simple ‘year’ column in your data.

Label visibility

Decide whether a label should be visible or not from the filter result. Nodes and edges not in the filtered graph will have their labels hidden. Can be reset by the ‘Reset Visible’ action (left of graph window).

Copy and Move to a workspace

New option when right-clicking on the graph. You can copy or move the selection to a new or existing workspace.

Import ‘Missing Nodes’ option

New option in the import panel to import nodes which were not properly defined in the file. Use this option to create nodes only from their reference in edges.

Import Time Frame

Their are different way to import longitudinal network in Gephi. One of them is to import multiple ‘static’ files, where each is a particular snaphsot in time (one file per day or per month). There is a new option for that in the import report. See this tutorial section to use it.

Time Frame settings

Decides whether the time format is a date or a real number. The processor will look for existing elements in the workspace and append the time frame to nodes and edges. The network becomes longitudinal, each node, edge and attribute is defined with time intervals.

Preview Presets

The Preview settings has now default presets: Default Curved, Highlight Mutual Edges, Small Labels and more.

Rescale weight in Preview

New option in preview to have edge weight look the same as Overview. Meta-edges have also now a separate scale slider in Visualization settings. This scale value is used in Preview to respect dimensions.

Original color option

When edges color are imported from a file or set by Partition, they have a custom color. This color mode can now be rendered by Preview by setting ‘Original’ in the color dialog.

Localization

Localization is now possible in Gephi, French and Spanish versions will be available soon. Please consider helping us, show up on the Translations forum section.

Gephi 0.7 alpha4 released

The alpha4 version has just been released, check out Download page or Check for Updates in your Gephi. This release comes with new features, including PDF export and bugfixes. Thank you to all members that reported bugs on the forum or through the Crash reporter, that helps a lot, more than you think!

Many bugs have been fixed, including the Menubar problem on Mac OS X and some annoying filters issues.

Let’s have a look on what’s new, and read the complete release notes.

PDF Export

The built-in PDF Exporter is now fully working. It exports the network exactly how it’s displayed in the “Preview” window. We have been impressed how fast it’s processing and exporting. One can configure the page size and margins, in addition to the orientation. Thus you can directly export your network and embed or print it anywhere. Note that texts in PDF are searchable, very useful. Special thanks to Jeremy Subtil who worked on his free time on this feature.

GraphML Export

Files in GraphML format can now be exported from Gephi. Interoperability is very important and the GraphML format is well known and supported in other tools such NodeXL, igraph or NetworkX. We hope that we reach interoperability with these tools and that we use GraphML in the same way. If not, please let us know.

Ego Network

A new filter has been created, it let’s you filter the graph from a node at depth 1, 2, 3 or Max. Enter a node label and the depth and it shows the network around this node.

Gephi 0.7alpha2 released

Gephi 0.7 alpha2 was just released. It increases stability and fix issues that were reported on our forum and bug tracker. Thanks for your valuable feedbacks!

Normally, for minor versions like those, Gephi updates itself by asking users to update when Gephi starts. This AutoUpdate feature was not yet available for 0.7alpha but is working now. Therefore users need to download this new 0.7alpha2 version to profit for upcoming updates through the plugin center.

Check releases notes and download latest version. Please uninstall previous versions first before installing it.

One can find many network and graph datasets on this wiki page.

Gephi’s 100-Day Plan

Gephi team is very proud to announce 0.7 version of the software, after almost one year of hard, yet passionate work. You can download and try the alpha version with various datasets. Please give us all feedback on our new forum.

Gephi is turning now in a fully collaborative free software project, as its software architecture allows collaborative development. The 0.7 project was a complete rewriting of the code in a modular way. Features were spitted in modules that can be developed and managed by different developers more easily. The Google Summer of Code 09 was a perfect way to experience our architecture. The modules developed at that time are now fully integrated in the 0.7alpha release. We plan to have many developers interested by creating plugins for Gephi. We oriented our new website in that way, have a look on the Plugin Center. Plugins could be anything, from a new layout algorithm to the connector that build graphs from your enterprise data. If you’re interested, please join the discussion on the forum.

We hope to collaborate with the entire community to help drive network visualization forward. Gephi’s aim is not only proposing unseen features, but above all build a professional tool that works and serve community’s needs.

Official 100-Day plan, presented as top priorities first

  • Fix all reported bugs and improve usability. The 0.7 beta version will be released.
  • Fill users’ Quick Start guide and create a simple tutorial how to use Gephi.
  • Documentation, documentation and more documentation.
  • Make a feature-madness video, to let people know us.
  • Create tutorial pages for plugin development. At least layout, metrics and import.
  • Fill the Plugin Portal documentation on the wiki.
  • Create a Manifest and fill “Goals and Aims” on the website. Share our passion for graph visualization and highlight most challenging tasks.
  • Start Gephi Student Program, by proposing a set of programming tasks that can be managed in a semester or a quartile by computer science students.
  • Post blog articles about our approach and how Gephi is different (and great!).
  • Reorganize 0.7 specifications and build a clear roadmap and a discussion space for future developments. Invite people to join the specification team.
  • Finish documenting Gephi’s API.
  • Give more insight which dataset Gephi can deal with, get closer from users’ needs by learning which networks they wants to visualize and support them in this task.

Please consider joining us for achieving these tasks! See the wiki.
