============
This is a demo of making great circle plots in R from airport codes
using a very bad map projection. I mean the point is, it's cool
looking. Map, archs, points, geo-locating. Pretty neat. Get a dump of
your fight data and map where you've been and what airline.
Then you'll realize, while pretty, it's kinda worthless as a
visual. So then we make a treemap. None of that pesky math, and it
tells you much easier where you go and on what carrier.
## Setup ##
The code here is setup to use a dump
from [openflights.org](http://openflights.org/) but the sample data is
just a subset. The full code is inline and commented out if you get a
full export. We'll make a pretty map with great circle plots to show
you every where you flew. Then we'll break it down by carrier.
For the point of this instructional, you'll need the following librarires:
* `car`
* `maps`
* `ggplot2`
* `geosphere`
* `parallel`
* `treemap`
The `parallel` package is just fun of it really. I mean I have
several cores, why not use most of them. The code itself is documented
explaining the step by step. Just source the `start.R` code. This
code was put together for a talk to
the [Singapore R Users group](http://www.meetup.com/R-User-Group-SG/)
and then expanded for
a
[WWW 2017 tutorial](https://sites.google.com/view/geocycle-www17/home)
The data in `flights.csv` is fictional. Just so you know that Virgin
America ~~doesn't~~didn't have a SFO to SFO flight. There are several good
[Airport Databases](http://www.partow.net/miscellaneous/airportdatabase/)
around the web too.
