MINI Circuits Everywhere!

Tomorrow I will be shipping my 400th auto up windows MINI circuit! I had this crazy idea to produce a USA map showing where they all have been shipped – so I gathered the ZIP code of every shipment into a spreadsheet, then tried to find a way to plot them on a map.
I was stumped, so called for help on MINI2 and quickly got a very useful reply from Jason (snid on MINI2). He directed me to TIGER Map and a couple of pages which gave enough hints to get the job done:


Producing this map is not difficult with TIGER Map – but that service is now gone …

Anyway the map unsurprisingly shows a concentration of MINI circuits to the east and west coast of USA, especially Boston, New York, Washington DC, Miami, San Francisco and Los Angeles. But there is also a cluster around Atlanta and around Dallas – I presume there is a MINI dealership at each location.
The Boston area is also (negatively) skewed because of the MINI circuits I have personally installed or delivered; I don’t have a ZIP code for those people!
In addition to the US mainland, there are MINI circuits in Hawaii, Puerto Rico, Canada, England, Germany, Switzerland and Austria!
