As a user, I want to see an interactive graphical representation of the data

The data should be visualized according to the following subtasks

• The data is presented on one or more web pages.
• At least one diagram is presented to the user.
• The data is explained so that the user knows what he/she is looking at
• There are controls to filter data in order to customize the visualization.
• The data do not need to be updated in real-time from the source.
