This yFiles AJAX demo application shows how to pull status data and other information from the server through polling, and how to update the client visualization according to the remote data.

Things to try out:

• Click a row in the status table: the corresponding node will be highlighted and centered.
• Turn server polling on and off using the "Poll" toggle button in the toolbar.
• Select a different polling interval (change will take effect after the currently queued request completes).
