This new Gephi release delivers a massive upgrade in performance, and our most reliable version to date. The Gephi team has long dreamt to rebuilt Gephi’s OpenGL visualization engine from scratch. The day where this hard work finally hits our dear users has come, alongside many new exciting features and more than 50 bug fixes.
Checkout the official release notes for expanded details on what’s new, and download Gephi 0.11 on our website!
New Features
New Visualization Engine
Gephi accelerates graph visualization via its OpenGL engine. The legacy engine was originally built in 2008 and wasn’t taking advantage of all the rendering improvements graphics card and OpenGL have made over the years. We’ve rewrote Gephi’s engine from scratch, harnessing massive performance gains along the way, while maintaining compatibility with older hardware.
Gephi can now easily visualize up to 10M elements on modern hardware. This is a 30x improvement compared to previous versions.
In this 0.11 release, our goal was to have feature parity with the legacy engine. Therefore, the way networks look on Overview hasn’t changed and we haven’t introduced many new features. We’ve built new foundations that will allow us to extend features in future versions.
We’ve however remodeled the settings panel with enriched and clearer options, to customize the way the graph looks.
Seamlessly switch between Overview and Preview
To improve usability, we’ve made the transition between the Overview and Preview perspective more seamless. We’ve notably focused on edge thickness and labels. For instance, now by default Preview uses the same font size and scale as Overview. It’s still possible to customize the font in Preview thought.
Explore the graph with your mouse
We’ve filled another usability gap with a new “Attributes” panel that shows the attribute values of the currently selected node. This new experience is well integrated into our new visualization engine, responding to mouse movement.
The existing “Edit” feature that was accessible from the toolbar has been merged with the new experience.
New option to avoid label overlap
A new toggle button was added to the Visualization settings. When turned on, labels no longer overlap and the largest ones are chosen first.
The same feature is also available in Preview, and can be customized. Note that it remains possible to finely control which label should be visible, via the Filters panel.
Transform in one click
Common transformations like Expand or Rotate previously required multiple clicks to be performed. We’ve made them more accessible in the Layout panel, in one-click. In addition, we added a Mirror transformation, which was previously missing.
We kept the legacy Contraction, Expansion and Rotate Layouts for now but will remove them in the next release.
New icons
We’ve refreshed all icons to make them more intuitive and consistent. Both light and dark modes are supported.
Support for Greek, Hungarian, Swedish and Ukrainian added
New languages have reached the minimum threshold of translation completion to be included as a new supported language: Greek, Hungarian, Korean, Swedish and Ukrainian language. If you want to contribute to localization, head to our Weblate project and get started.
New default settings and presets
Default values that persist across Gephi executions are set in Settings. We’ve added a lot more of those “Default settings” across Visualization, Layout, Appearance, Preview and Attributes to increase usability and customization capabilities. For instance, one can create a Preview preset and set it as the default.
Layout Presets were also improved, so that one can choose a Default Preset applied to a Layout.
We’re excited for you to try the new version! We want to thank everyone who contributed to the release and especially the beta testers who give us valuable feedback.
Compatible plugins have already been published. We’ll review the missing ones shortly.
