As an ameturer programmer (one without proper trainings in any mainstream programming language — C and Java) , the more I use R the more I understand the saying — “You are only bounded by your imagination”.
The other day I suddenly recalled that someone did a very impressive Facebook map. I then thought it would be nice if I can put these “flows” on the map (or of the same sort) created in my first post. So, I googled around and found this brilliant blog that teaches you how to make flows (Great circles) step by step.
Again, thanks to R, its great community and its openness, I created the following map of international weapon export in 2010 (from top 7 exporters). I hope someone who knows about weapon exports could share some stories with us. But, let’s all pray for PEACE.
