Features

yFiles for HTML brings the features of the yFiles family of diagramming programming libraries to the web platform. It features UI components for the display and intuitive user interaction with diagrams and the automatic graph layout algorithms and graph analysis algorithms.

Unique features of yFiles for HTML

100% Client-Side

100% client-side graph drawing and graph editing in HTML5-capable browsers— no server component or browser plugin required.

Latest Drawing Technologies

Leverages both SVG, WebGL, and HTML5 Canvas to draw diagrams. The three technologies may be combined and used at the same time for the ultimate user experience.

Optional Server Components

Optional server components (node.js / Java / .NET) for automatic diagram layout and computationally-intensive tasks.

Flexible Loading

Develop using your favorite tool-chain: Use Webpack, UMD, AMD, Browserify, angular-cli, native ES6 modules, simple script loading, and more.

Optional GWT Overlay

Optional GWT overlay for the development with GWT Web Toolkit (GWT).

Pure Javascript

A pure JavaScript solution that works seamlessly with AngularJS, Angular 2+, ReactJS, Vue.js, and basically any other JavaScript framework.

Supports ECMAScript 6

Requires ECMAScript 5 at minimum at runtime, but the API supports the new features of ECMAScript 6 like async functions and Promises, classes, ES6-modules, iterators, etc. at compile time.

TypeScript Support

Direct TypeScript support with complete TypeScript bindings for all members.

Developer Support

Extensive developer support with Developer's Guide and API documentation viewer, and with debug support, runtime type-checking, code completion, and quick API lookup in many IDEs.

Live Demos

The demo applications showcase the visualization and interaction capabilities of the yFiles for HTML diagramming software library.
See the versatility of the library and the possibilities it offers for your own applications!

Layout Styles

The Layout Styles demo showcases the various automatic diagram layout algorithms of yFiles, including hierarchic, organic, orthogonal, tree, circular and balloon styles. Additionally, it presents the powerful and highly customizable graph editing capabilities of the graph component.

Graph Analysis

The Graph Analysis demo application showcases a selection of algorithms such as shortest paths, flows, centrality measures, etc. that help analyzing the structure of a graph.

Large Network Visualization

The Large Graph Visualization demo application compares the and presents the three different supported rendering technologies of yFiles for HTML and shows how to combine them:
  • Switch between WebGL, HTML5 Canvas, and SVG rendering
  • See level of detail rendering and mixing technologies
  • Benchmark visualization performance of larger networks.

Organization Chart

The Organization Chart demo application shows how to create an interactive organization chart with data loaded from JSON.

Collapsible Tree

The Collapsible Tree demo application displays a tree-like structure that can be expanded and collapsed interactively. The nodes are rendered with custom icons that indicate their current state. After an expand or collapse operation, the graph is redrawn using a configurable layout algorithm.

Graph Viewer

The Graph Viewer demo application demonstrates user interaction possibilities such as zooming, panning, overview, and toggling additional node information.

Grouped Graph

The Grouped Graph demo application presents the grouping support of yFiles for HTML. Group nodes can be collapsed or expanded. Additionally, when a group node is expanded or collapsed, a new incremental layout is calculated and the graph is redrawn.
