### Minimal GoJS Diagram Setup

Source: https://github.com/northwoodssoftware/gojs/blob/master/README.md

Demonstrates the basic HTML structure required to host a GoJS diagram and the minimal JavaScript code to initialize a diagram, define a simple node template, and load model data. Requires the GoJS library to be loaded.

```HTML
<div id="myDiagramDiv" style="width:400px; height:150px;"></div>

<script src="https://cdn.jsdelivr.net/npm/gojs/release/go.js"></script>
```

```JavaScript
  const myDiagram =
    new go.Diagram('myDiagramDiv', { // create a Diagram for the HTML Div element
      'undoManager.isEnabled': true  // enable undo & redo
    });

  // define a simple Node template
  // the Shape will automatically surround the TextBlock
  myDiagram.nodeTemplate =
    new go.Node('Auto')
      .add(  // add a Shape and a TextBlock to this "Auto" Panel
        new go.Shape('RoundedRectangle', { strokeWidth: 0, fill: 'white' }) // no border; default fill is white
          .bind('fill', 'color'), // Shape.fill is bound to Node.data.color
        new go.TextBlock({ margin: 8, font: 'bold 14px sans-serif', stroke: '#333' }) // some room around the text
          .bind('text', 'key') // TextBlock.text is bound to Node.data.key
      );

  // but use the default Link template, by not setting Diagram.linkTemplate

  // create the model data that will be represented by Nodes and Links
  myDiagram.model = new go.GraphLinksModel(
    [
      { key: 'Alpha', color: 'lightblue' },
      { key: 'Beta', color: 'orange' },

```

### Installing GoJS Library via npm

Source: https://github.com/northwoodssoftware/gojs/blob/master/README.md

Command to install the core GoJS library package using the Node Package Manager (npm). This provides the necessary files to use GoJS in a project.

```Shell
$ npm install gojs
```

--------------------------------

### Creating GoJS Project Kit via npm

Source: https://github.com/northwoodssoftware/gojs/blob/master/README.md

Command to create a new project kit containing GoJS samples, extensions, and documentation using npm. This is useful for exploring the full GoJS ecosystem.

```Shell
$ npm create gojs-kit@latest
```

### Defining GoJS Model Data - JavaScript

Source: https://github.com/northwoodssoftware/gojs/blob/master/README.md

This JavaScript code defines the node data array and the link data array for a GoJS diagram model. It represents a simple graph structure with five nodes and five links, including a self-loop.

```javascript
      { key: 'Gamma', color: 'lightgreen' },
      { key: 'Delta', color: 'pink' },
    ],
    [
      { from: 'Alpha', to: 'Beta' },
      { from: 'Alpha', to: 'Gamma' },
      { from: 'Beta', to: 'Beta' },
      { from: 'Gamma', to: 'Delta' },
      { from: 'Delta', to: 'Alpha' },
    ]
  );
```
