Description

This demo shows how to run a yFiles layout algorithm in a Web Worker task in order to prevent the layout calculation from blocking the UI.

To transfer the graph structure and layout between the worker and the main page, a simple JSON format is used. As the web worker environment does not support any DOM-related functionality, the GraphML format can't be used for this purpose.

Things to Try

Modify the graph structure by adding/removing nodes and edges, and re-run the web worker layout.
