What it does

GoJS is a JavaScript library for creating interactive diagrams, flowcharts, and visualizations in web applications.

When to use it
  • •Building a web-based project management tool with customizable workflow diagrams
  • •Creating an interactive org chart for a company's internal directory
  • •Designing a visual programming language for educational or development environments
Ready-to-paste prompt
diagram.model.addNode({ text: 'Decision', locale: 'en' }); diagram.model.addLink({ from: 'Start', to: 'Decision' });
Heads up: Make sure to include the necessary GoJS modules and extensions in your project, as some features require additional imports, such as the 'gojs/extensions/TreeLayout.js' file for tree layouts.
