## What it is
Piecon is a tiny JavaScript library that dynamically renders progress pie charts directly in a page's favicon, with retina support. It falls back to updating the document title with the percentage in browsers that don't support canvas favicons.

## Use cases
- show upload or download progress in the favicon
- display background task progress without a visible widget
- indicate page loading percentage in the browser tab
- render a dynamic pie chart icon in the favicon
- show progress in the tab title as a fallback for unsupported browsers

## When to choose
- you want a lightweight, dependency-free way to show progress in the browser tab
- your app performs long-running background work and users switch tabs
- you need retina-crisp favicon graphics

## When to avoid
- you need full-featured charting or dashboards
- you must support browsers without canvas favicon support with graphical output
- you need an actively developed library with recent commits and a repository license file

## Facets
- artifact type: library
- maturity: maintenance
- function: data-visualization, charts
- domain: web-development, frontend, data-visualization
- platform: browser
