Circle Tag Cloud is a lightweight and customizable plugin that displays your tags (or any taxonomy) in a visually striking, packed layout. Unlike traditional tag clouds, it uses a smart JavaScript packing algorithm to arrange terms tightly within a circle or rectangle without overlapping.
It is designed with performance and accessibility in mind, featuring a built-in caching system (Transient API) and keyboard navigation support.
Key Features:
<ul>
<li>Smart Packing: Automatically arranges tags in a dense Circle or Rectangle shape.</li>
<li>Color Palettes: Choose from preset palettes (Warm, Cool, Vivid, Monochrome, Metallic Mix) or define your own Custom Colors.</li>
<li>Smart Contrast: Automatically adjusts text color (black or white) based on the background color for optimal readability.</li>
<li>Text Outline: Adds a “Glow” effect outline to text for better visibility on any color.</li>
<li>Motion Effect: Optional subtle floating animation (respects “prefers-reduced-motion” settings).</li>
<li>High Performance: Uses Transient API caching to minimize database queries.</li>
<li>Accessibility Ready: Full keyboard navigation support with tooltips that appear on focus.</li>
<li>Easy Configuration: Manage everything from a dedicated settings page or override via shortcode attributes.</li>
</ul>
Usage:
Simply add the shortcode <code>[circle_tag_cloud]</code> to any post, page, or widget.
You can also specify attributes directly in the shortcode: 
 [circle_tag_cloud taxonomy=”category” max=”30″ shape=”circle” palette=”metallic”]
