Graphs are planned for both the team and personal stats.
I'm in the process of building a general-purpose graph function, it is working now but still rather limited. The real world has been demanding attention recently, this has greatly slowed new stats features.
Once the function is complete, the code backbone for the data will have to be created, that part will (probably) not be too difficult. However, basic Folding stats are going to be needed soon.
Please be patient, graphs are coming.
