## What it is
A web application that visualizes Codeforces competitive programming user data via the official Codeforces API. It provides charts of verdicts, languages, tags, and rating timelines, plus side-by-side comparison of two users.

## Use cases
- visualize my codeforces submission statistics
- compare two competitive programmers' ratings
- see which problem tags I solve most
- track my codeforces rating history over time
- find unsolved problems on codeforces
- show a heatmap of my daily submissions

## When to choose
- you want quick charts of a Codeforces user's performance without setup
- you need head-to-head comparison of two competitive programmers
- you want a hosted tool with no login required

## When to avoid
- you need analytics for judges other than Codeforces
- you need offline or API-independent operation
- you require a maintained library with a license for embedding

## Facets
- artifact type: application
- maturity: active
- function: data-visualization, charts, http-client
- domain: data-visualization, developer-tools, education
- platform: browser
- tags: codeforces, competitive-programming, google-charts, jquery, analytics, static-site, web-server, javascript
