Any software to read csv from custom data logger?

Hello,

I'm in the process of creating custom OLED screen simple dashbord to suit my car's stock ECU. It's equipped so far with K-Line, CAN bus, knock sensing, two low side PWM outputs, EGT and few analog inputs. It's still in prototype form but it logs data to internal memory that I can analyze later. So far what I did is creating a csv file but I'm wondering if there are any advanced software that I can use to create graphs, maps etc. with simple csv file.

If there's known and described logging protocol of any big players like ECU Master or Motec, I can edit my logging system to create files like those and use their systems and log viewers. But is there something like that widely available?
