The purpose of this assignment is to determine the best fit model among the available trend models, such as linear, quadratic, cyclical/seasonal and cosine. Also, we have to provide the predictions of annual ozone thickness changes for the upcoming 5 years, by using the chosen best model. Further, we have to propose a set of possible ARIMA(p, d, q) models, using each and every model specification tool such as ACF, PACF, EACF, BIC table and other tests.

Part 1: Find a problematic data visualisation, Part 2: Deconstruct - State the objective, target audience and issues with the chosen data visualisation, and Part 3: Reconstruct - Use ggplot2 to fix the identified problems with chosen data visualisation.
