Circuit corresponding to positively skewed bode plot
simulate this circuit &ndash; Schematic created using CircuitLab

You know that the gain is dropping rapidly with decreasing frequency, so you can suppose that the circuit is capacitor coupled.  You have a resonance so you can suppose that there's another reactive element like an inductor.  You have damping, so you have some resistance, and you have 0db of gain at high frequencies, so the bottom divider element must go high impedance at high frequencies (i.e. it's inductive).  

Something like a capacitor from the input to output with an inductor and resistor in series from the output to ground would give a response like this.
