The National Flood Insurance Program (NFIP) by the Federal Emergency Management Agency (FEMA) in the United States enables property owners in participating communities to purchase insurance protection from the government against losses from flooding (http://en.wikipedia.org/wiki/National_Flood_Insurance_Program). A number of studies in the recent past have analyzed the NFIP and also its feasibility.
To my knowledge, there is no readily available code to analyze the data and other statistics on NFIP provided by FEMA (http://www.fema.gov/policy-claim-statistics-flood-insurance/policy-claim-statistics-flood-insurance/policy-claim-13).
Here is my attempt to clean and format the data from FEMA and also here are some interesting graphics.

I wanted to make these maps interactive using googleVis, but googleVis does not seem to have the capability to do so at the resolution of a county (it only seems to work for state and metro resolutions).
