As you can see in the picture below, the diagram is shifted to the left. The code I am using to display this image is give below:
\begin{center}
\includegraphics[width=\textwidth]{"Law 2".png}
\end{center}
The name of the image file is "Law 2". How should I go about fixing this problem? I've also read answers to a related question, but, since I am a beginner in Latex, it's difficult for me to understand their logic. So, an ideal answer would be one that strictly deals with my case.

Experiment with various values instead of 20 until you get a satisfying output (keep\fboxduring the attempts). Or clip the image with some specialized software. – egreg Jun 16 '16 at 17:58
