title: Looking for a rails gem for simple BI tasks
body: <p>I'm imagining a rails gem that I can feed with a list of SQL queries such as <code>count (*) from users where active = 1</code> and this gem would provide a rake task that I can run as a daily cron job and have a graphic interface that plots the results as a graph. For example, one graph for number of daily active users, another graph for number of new registrations etc. A very simple and basic BI for my rails database.<br>
  It might be simple enough to implement, still, I'd be happy to find a prepackaged gem.<br>
  Googling didn't find one, anyone knows one?<br>
  thanks!</p>
