File Operations Demo

This demo shows various ways to open and save a graph.

Things to Try

• Edit the graph and save it in JSON or GraphML format in one of the available ways.
• Open a previously saved graph.

Open

Open a graph from file with a file chooser dialog. This is based on the FileReader API.

Save

Download

Download the graph as file.

New Tab

Show the file content in a new browser window.

Local Storage

Open and save the graph using the Storage API.

JSON data model

For JSON data handling, this demo uses types and functions defined in json-model.d.ts, json-support.ts and json-writer.ts.

These type definitions and functions provide simple and, for many use cases, complete functionality for processing graph data for a yFiles application.
