This is a demonstration of how one could easily make a twitter analytics dashboard. This demo shows live analytics of actual twitter data that is gathered through the Twitter API. A processor runs some simple algorithms on the data and then publishes results to the Emitter broker. Any user can now subscribe to receive this data and to use it in a dashboard.
The dashboard displays the fraction of re-tweets and the number of tweets created per second. One could do this for specific hashtags and in such a way create a twitter analytics dashboard. The source code provided above could be a good starting point.
