Objective 1 (Easy): Clean data by removing addresses without real city names and extract country out of their addresses.
Objective 2 (Easy): Count the total number of EV charging stations by city and find the top ten cities.
Objective 3 (Easy): Of the top ten cities, find out which cities have the cheapest average cost to charge per kwH and show the five cheapest cities.
Objective 4 (Medium): Create a bar chart that allows you to compare the top ten cities in terms of average cost to charge per kwH. Create a widget that lets you select the cities you want to see in this plot and control the plotting with flow variables.
