We are currently using the sample shapefile provided as part of the Silverlight DataVisualization samples package (usa_st.shp and usa_st.dbf) and it is pretty close to our needs.  We would however like to have Alaska, Hawaii, Puerto Rico at their correct coordinates and size (Alaska on the sample shapefile is very small).  I have looked at the other shapefile sources you listed in your documentation, but any shapefiles provided by these sources are much bigger (filesize) than your sample shapefile.  Can you provide a copy of the shapefile with these states in their original location (not in the Gulf of Mexico) or how would I edit the shapefile and get these states back to their original position?
