Create a simple Air Quality Assessment Tool using the technology of your choice ( java, python, nodejs, or even a web front end framework) that utilizes Open AQ Platform API. It will have the ability to compare the Air Quality of two cities.
The tool must:
- Allow the user to input two cities
- Display the air quality of the corresponding cities, allowing the user to compare the two
- Gracefully handle any API or user errors
- Tool should be easily used by the general public
