add plotting feature in the pipeline

[dnabanita7]

As discussed I want to add the plotting feature in the pipeline so that whenever we need we can visualize the data.

i suggest you include an argument to the mutable structure function that indicates which columns to plot for either 1D, 2D, and 3D plots. also for classification problem, plotting the bargraph or pie-chart of the distribution of different classes will be helpful.
