Working with the Crime Severity Index has been an interesting exercise.

Generally speaking, severity of crime is not correlated with the volume of crime committed, but there are certainly some outliers.

The airports and routes data can be manipulated, combined and cleaned-up to create a complimentary table that lists the longitude and latitude of each flights origin and destination. This allows us to connect each flight origin and destination. However, straight lines of Continue reading »
