General goal: Extend the user pages from the previous lecture with simple visualizations.

Submit your source code to /submit/javascript/username/. Also do not forget to submit the database (even if it is the database from us).

This lesson requires a database with crawled data and a webserver from previous lessons. If you don't have one, you can find it at /tasks/javascript

Task B
