Analyzing and visualizing data

Take the assignment from the previous week, add at least twice as much data to the data sets.  Note how this impacted the results from the previous week.  Be sure to have a visualization to show the initial results and the new results.  Be sure to explain why the results are different or similar from last week. 

Below one is previous assignment :

 Review The Power of Good Design and select three of the ten principles noted for good design. Next in R, utilize these three principles in a problem that you will solve. First note the problem to solve, the dataset (where the information was pulled from), and what methods you are going to take to solve the problem. Ensure the problem is simple enough to complete within a two-page document. For example, I need to purchase a house and want to know what my options are given x amount of dollars and x location based on a sample of data from Zillow within each location. Ensure there is data visualization in the homework and note how it relates to the three principles selected. This is previous assignment which you have done
