Plotting data with C++

We plot with the plotcpp library, which is a thin wrapper around the gnuplot command-line utility. With this library, we can draw points on a scatter plot or draw lines. The initial step to start plotting with this library is creating an object of the Plot class. Then, we have to specify the output destination of the drawing.
