Assignment 2 Tony Yao on Gasoline retail price

What I found quite interesting is that the average gasoline retail price for New York State is getting lower from year to year. Despite the fact that living expenses are getting higher and higher, the gasoline price is getting lower. Also, in each year, the price are also fluctuant which indicates that there might be other factors that are interfering gasoline price.

I create two charts. The first one is to show the price changes in all counties throughout the year. The second one is to show exact gasoline average price week by week and shows which county has the higher price that week.
