Suitable layouts for every use case
Choose from a huge number of predefined layouts and configure them to perfectly fit the task at hand.
yFiles provides the widest range of high-quality automatic layout arrangements in the industry. Over a dozen different implementations with several hundred different settings let you fine-tune the results. With the right algorithm and configuration, you can add relevant information to visualizations, helping users find answers to their questions, simply by looking at the diagrams.
Incorporate business data, graph analysis results, and user input to drive the configuration and highlight key aspects. Use animation to blend between different layouts and help users keeping their mental map with smooth incremental changes.
Countless interaction possibilities
You decide what your app can do. Easily customize the interaction with graphs and diagrams, for efficient, intuitive work on your use case.
Use keyboard, mouse, touch, and pen input to interact with the diagrams and data. Provide dynamic help, visual feedback, and tailored interactions to provide the best possible user experience.
Customized, meaningful designs
Include all of the information you want to show – within the design itself.
Adjust the design dynamically to the zoom level or data updates. Show dynamic data as part of the visualization and depending on the context. Add interactivity and reactivity to the diagrams. Configure your design to show just the amount of information your users require.
Enjoy automatic layouts
Assist your users as they create and explore their diagrams. Use automatic layouts to build clear and beautiful diagrams from your data at the touch of a button.
Automatically update your visualizations when data changes, while maintaining a consistent design. Highlight important aspects in both the structure and the meta data of your diagrams.
Create intuitive interaction
Accept no limits. Implement the perfect interaction design that will make your users productive, no matter whether these are casual or power users.
Connect all types of data sources
yFiles can handle all types of relational data, no matter where you store it or how you create it.

Integrate yFiles in your system
yFiles will perfectly enhance your existing application or framework. Technically as well as visually – by reflecting your corporate design or the app’s look and feel.
No Matter what technology you are using. Add yFiles to existing apps, dashboards, and reports, or create new stunning apps that seamlessly integrate with your line of products' look and feel.

Our annual major release for yFiles for HTML (v.2.5) has been rolled out – with many new choices and features. We’ve prepared a deep-dive article and, of course, very detailed release notes. Have a look!
A quick note for .NET and Java users: yFiles for your platforms will be rolled out gradually.

Again this year, yFiles expands its palette of versatile, automatic layouts. One highlight is the new Cactus Group Layout , which lets you visualize groups with a strong emphasis on their grouping hierarchy, as well as the new Compact Disc Layout, which densely arranges nodes around a common center point.

And that’s not all! The upcoming release offers an array of fresh visualization options: an all-new flexible group node, arrow-shaped nodes and edges, and custom label shapes, just to name a few. When it comes to the look and feel of your application, the sky’s the limit.

We also worked hard to extend the WebGL2 rendering mode – from additional animations, to new highlight and selection effects, to greater visual fidelity and performance, to improvements in style persistence.

Throughout the SDK, we’ve refined many of the interaction elements, so yFiles will surprise you with plenty of small innovations, in terms of handling as well as design.

Creating beautiful, up-to-date graph applications is easier than ever!
