Just KNIME It S04 _ CH01 _ Best Places to Live with an EV
Level: Medium
Description: You have an EV and want to live in a place that has many available charging stations, and where it is also cheap to charge your vehicle. Given a dataset on chargers around the world, you need to find out the top ten cities that have the most EV chargers. You also want to consider which of those ten cities offer, on average, the cheapest KwH rates in cost. You should be narrowing down your city of choice to five after taking into account the costs.
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.
