cytoscape-html

cytoscape-html allows you to render arbitrary HTML as nodes on the graph

Installation

npm install cytoscape-html

Getting Started

1. Import the Extension:

First, import the extension and Cytoscape.js library into your project:

 import cytoscape from 'cytoscape';
 import cytoscapeHTML from 'cytoscape-html';

2. Initialize Cytoscape with HTML Nodes:

Create a Cytoscape instance and enable the HTML nodes extension:

 cytoscape.use(cytoscapeHTML);

 const cy = cytoscape({
   container: document.getElementById('cy-container'),
   elements: [...], // Define your network elements here
   // Other Cytoscape options...
 });

3. Add HTML Nodes:

Create nodes with an html field

 const elements = [
   // ...other elements
   {
     data: {
       id: 'html-node-1',
       html: '<div class="node-content">This is an HTML node!</div>',
     },
   },
 ];
 
 cy.add(elements);

4. Render the HTML:

To create an HTML node, define a node in your elements array with the html field:

 // tell cytoscape-html to render the nodes with a data.html attribute
 cytoscape.nodes().renderHTMLNodes();

You may also hide the underlying node with hideOriginal:

 cytoscape.nodes().renderHTMLNodes({ hideOriginal: true });

Styling and Interaction:

You can style your HTML nodes using CSS classes, and you can attach event listeners using Cytoscape's event handling mechanisms.

Example

An example is included in the /example directory. This example demonstrates:

• Creating three colored nodes (red, green, and blue) with custom HTML content
• Using the renderHTMLNodes function to render the HTML content

To run the example:

1. Build the extension: npm run build
2. Open the example/index.html file in your browser
