Add diagram resources (scripts and styles) onto the page.

anddx-diagram.min.js
files to your page.HTML<link rel="stylesheet" href="node_modules/devexpress-diagram/dx-diagram.min.css"> <script type="text/javascript" src="node_modules/devexpress-diagram/dx-diagram.min.js"></script>

anddx-diagram.min.js
files to your page.HTML<link rel="stylesheet" href="https://cdn3.devexpress.com/jslib/19.2.15/css/dx-diagram.min.css"> <script src="https://cdn3.devexpress.com/jslib/19.2.15/js/dx-diagram.min.js"></script>
Local Scripts
You can find all the required files in the DevExtreme zip archive or DevExtreme folder (%ProgramFiles(x86)%\DevExpress 19.2\DevExtreme\Sources). Copy the dx-diagram.min.js and dx-diagram.min.css files into your application folder. Then, link the required files.

Use the the dx-diagram.css
and dx-diagram.js
files to add an unminified version of the resource files to your page.
The Diagram widget is a jQuery DevExtreme widget, and thus requires common DevExtreme resources (listed below) to be included into your page.

Initialize the Diagram widget in a DOM element.
$(function() { $("#diagram").dxDiagram(); });
<div id="diagram"></div>
Load and Save Diagram Content
To load and save a diagram to a string variable, use the import and export methods.
var diagram = $("#diagram").dxDiagram("instance"); var diagramContent = diagram.export(); // load diagram content to a variable diagram.import(newDiagramContent); // replace the existing diagram with a new diagram
