# Codeforces Visualizer

This is code repository for a simple analytics visualization site for [Codeforces online judge](http://codeforces.com/) users using [Codeforces API](https://codeforces.com/apiHelp). The site is currently hosted at [here](https://cfviz.netlify.com/).

* List of unsolved problems

#### Comparison between two users

* Current, max and min rating

* Number of contests

* Best and worst position in contest

#### Issues

* When somebody searches for a handle that doesn't exists, we get  Cross-Origin Request blocked and the status code becomes 0 in jQuery. So we can't determine if the user doesn't really exists or some other network problem occurs.

* Firefox hangs for a while when drawing the tags comparison chart. Probably because it's big. I have plan to divide that chart in two parts.

* When counting number of solved problems, some problems that appear both on div 1 and div 2  get counted twice.
