Creating dynamic Peer Groups

I'm looking for direction on how I can create dynamic peer groups.  Basically what I'm trying to do is have the ability for a user to select a peer group (based on size, region, industry) and have that Peer Group populate in the report visuals.  The user could then see how their selected peer group compares to the rest of the respondents in each of the visuals.  For example, in a bar graph the x axis would have a bar for All Responses, a bar for Peer Group, a bar for Filtered Company. 

It has to be dynamic, meaning a user can change a demension of the peer group at will.  Can anyone direct me to an article, video, etc. that might give some direction on how to create?
