The process shown on the TV graph is a straight vertical line, which implies that the volume is constant. This means that there is no work being done, which happens in an isochoric process. The fact that the line is not horizontal means that the temperature is changing, so it cannot be isochoric. Additionally, the fact that the line is not sloped means that the pressure is constant, so it cannot be adiabatic or isobaric. The only process that fits these conditions is an isothermal compression.
