Am I reading it right? R generated that?

Am I reading it right? R generated that?
- chunkbot 16y agoYou're surprised? Why?
- gloob 16y agoI can't speak for the poster you're responding to, but if it's easy to make things that pretty in R, I suddenly want to learn it.
- marcinw 16y agoWe're all wondering what he used to visualize his data set.
- acgourley 16y agoMy experience with R is that it generates much more... utilitarian output.
- pragetruif 16y agoThe visualization definitely wasn't done in R. I'm guessing he used Gephi (see, for example, http://gephi.org/2010/map-geocoded-data-with-gephi/ http://gephi.org/2010/map-geocoded-data-with-gephi/).
- miguelrios 16y agoI bet you Gephi cannot handle more than tens of thousands of node.
- bajsejohannes 16y agoHow can you tell that it definitely was not done in R? He says > As a sanity check, I plotted points at some of the latitude and longitude coordinates. To my relief, what I saw was roughly an outline of the world. His plot doesn't "know" about the world - he is just drawing curves between points in a plane (lat. and long.). I haven't used R, but I am sure that would be possible.
- pragetruif 16y agoBecause I use R quite often, and R just doesn't produce graphs that look like that :). But yes, it's probably possible to draw an uglier version of the visualization. (I know you can draw the individual points on the plane, so drawing lines between points is probably available as well, though I'm not so sure about the great circles part.)
- bajsejohannes 16y agoOk. I believe you :) It just seemed simple enough that anything that could do graphics would be able to do it.
- nonfamous 16y agoYes, it was R. The author explains: http://paulbutler.org/archives/visualizing-facebook-friends/ http://paulbutler.org/archives/visualizing-facebook-friends/
