Based on the example in the slide and the mpl$\_$squares.py code provided to develop an application that supports the relationship of $y=x+3.$ You need to draw both a line plot and a scatter plot. The input $x$ values are $1,2,3,4,5$ and the corresponding $y$ values are thus be $4,5,6,7,8$

To complete the program $(10$ points$)$:

Create a module named h$12\_01.$py from the directory hw

Record your name, class number, and date of creation.

Based on the data provided above, create an application the draw a line plot and a scatter plot, and save to two files respectively.
