Piecon
A tiny JavaScript library for dynamically generating progress pie charts in your browser's favicon.
What is Piecon?
Piecon is a tiny JavaScript library that dynamically generates progress pie charts in your browser's favicon. It allows developers to visualize progress, such as uploads or task completion, directly in the favicon without requiring additional UI elements. The library is lightweight, customizable, and supports retina displays for crisp graphics.
Frontend developers and web designers looking to add subtle, real-time progress indicators to web applications without cluttering the interface.
Developers choose Piecon for its simplicity, minimal footprint, and ability to provide visual feedback in a non-intrusive way. It offers an easy-to-integrate solution with cross-browser support and customization options, making it ideal for enhancing user experience with minimal effort.

Pros & Cons
Pros
The library is minimal in size, ensuring no performance overhead, as highlighted in the README's feature list.
Provides crisp, pixel-perfect graphics on high-resolution displays, explicitly mentioned in the README.
Allows easy customization of pie color, background, and shadow via the setOptions() method, as documented.
Works in modern browsers and falls back to title updates for older ones like IE9 and Safari 5+, ensuring broader compatibility.
Cons
Only supports simple pie charts; cannot handle multi-part progress, animations, or detailed icons, which may be insufficient for advanced UIs.
Relies on fallbacks for older browsers, which only update the title bar, reducing the visual impact and user experience.
Changes to the favicon and title are not inherently accessible to screen readers, a concern not addressed in the README.
The README lacks guidance on error handling for favicon manipulation failures, which could lead to silent issues in unsupported environments.
