## What it is
A jQuery plugin that renders canvas-based dial/knob widgets, overloading input elements with touch, mouse, mousewheel, and keyboard support. It is highly configurable via data attributes or options, with hooks for change, release, draw, and formatting.

## Use cases
- add a rotary knob control to a web form
- replace a plain number input with a touch-friendly dial
- build audio mixer or volume controls in the browser
- create canvas-based gauge widgets without image sprites
- support keyboard and mousewheel value adjustment on a dial

## When to choose
- you already use jQuery and need a dial/knob UI widget
- you need touch, mouse, and keyboard input on a circular control
- you want a lightweight, dependency-light canvas dial with no image assets

## When to avoid
- you are building a modern app without jQuery
- you need React/Vue component ecosystems or TypeScript support
- you need accessibility features beyond basic keyboard input or active maintenance

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, frontend-framework
- domain: web-development, frontend
- platform: browser, cross-platform
- tags: jquery-plugin, dial, knob, canvas, touch-input
