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:

Smart Packing: Automatically arranges tags in a dense Circle or Rectangle shape.
Color Palettes: Choose from preset palettes (Warm, Cool, Vivid, Monochrome, Metallic Mix) or define your own Custom Colors.
Smart Contrast: Automatically adjusts text color (black or white) based on the background color for optimal readability.
Text Outline: Adds a “Glow” effect outline to text for better visibility on any color.
Motion Effect: Optional subtle floating animation (respects “prefers-reduced-motion” settings).
High Performance: Uses Transient API caching to minimize database queries.
Accessibility Ready: Full keyboard navigation support with tooltips that appear on focus.
Easy Configuration: Manage everything from a dedicated settings page or override via shortcode attributes.

Usage:

Simply add the shortcode [circle_tag_cloud] 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”]
