Geo chart - Response to Motion Chart Tutorial

This is a response to the video tutorial on motion chart.. I found a data set on cigarette smoker rates by state. I thought it would be valuable to create a geo chart so that it would be easy to notice the magnitudes by state. I know it is kind of hard to see in this picture, but in the actual chart you can focus in on certain parts of the map to better inter prelate.


From the heat map produced it is a little easier to see the magnitude of cigarette smoking rates by state.  It appears the states with the highest rates are those with more rural populations. Historically cigarette companies have marketed towards the blue collar portion of America (i.e Marlboro and Cowboys), and this helps explain the distribution seen above. It would be interesting to see a motion chart over time of the smoking rates as well..

The data can be found by the following link.

  1. Thanks for sharing. This is very interesting. Note that you can do some of this work on Matlab, please let me know if anyone needs an example M file
