jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful, optimized, platform-independent, and widely supported framework. The jqxTagCloud is used for displaying a set of user-generated tags that go with the articles, posts, or videos on a website.

- label: This is the label of the item.
- value: This is the value of the item.
- url: This is the URL of the item.
- visibleIndex: This is the visible index of the item.
- index: This is the index of the item.
