I see what you mean. If you want a cool and wavy graph that is not symmetrical, you can try the following function:

f(x) = sin(x) + sin(2x+0.3)/2 + sin(3x+0.6)/3 + sin(4x+1)/4

This function adds multiple sine waves with different frequencies and amplitudes, which creates a complex and visually interesting wave pattern. The addition of a constant to each sine function's argument causes a phase shift, making the graph asymmetrical. 

Try inputting this function into Desmos graphing calculator to see the cool and wavy graph it generates.
