How to plot positions on a map by longitude and latitude using D3.js. This uses the UK map data from http://bost.ocks.org/mike/map/

	# Where 'ts' is the time series (without transient behavior)
	# a <- as.data.frame(cbind(spectrum(ts)$freq,spectrum(ts)$spec))
	# b <- order(a[2], decreasing=TRUE)[1]
	# 1/a$V1[b] # !If this is the same as length(ts) then periodicity is 0(zero)

	periodicity <- function(ts){
	if (length(unique(ts))==1){
	# No need for spectrum analysis as all values are same. Periodicity is zero.
	return(0)
	} else {
