## Overview

egglog is a browser-based egg-weight logger and analysis tool for hobby hen keepers. The workflow is to enter weights for today, store them as Google Calendar events, retrieve egg events, and view recorded weights in a chart with month, season, and year navigation. The sampled JavaScript supports calendar event listing and mutations, weight parsing, and charting; some page wiring and unsampled implementation details are not verified.

Main entry points: [`js/egglog.js`](https://github.com/wingdingo/egglog/blob/master/js/egglog.js) (App behavior), [`index.html`](https://github.com/wingdingo/egglog/blob/master/index.html) (Web page)
