derivation of compressibility factor vs. reduced pressure

I am supposed to derive the graph by solving equations

2. Relevant equations

Van der Waals equation of state

compressibility factor, Z = (Pv)/(RT)

reduced pressure = P/critical pressure

Z = f(T_{r}, P_{r})

3. The attempt at a solution

I sat for 12 hours attempting to find a solution but just spent time trying to understand what I was doing instead.

Is there a way to get the graph mathematically without using any values for critical pressure or temperature?

Thank you!
