Location of India-Based Contractors on oDesk

My favorite R package, ggplot2, recently introduced enhanced support for choropleth maps. I'd like to make some of these kinds of maps with oDesk data, but as a first step, I thought I'd just plot the locations of all of our India-based contractors by city. In the plot below, dots size as log-scaled by # of contractors reporting that city. The massive light blue dot near Delhi is default coordinate when we're missing the city.

For those of you who know India, anything surprising/interesting here?

Here's the associated R code to make this figure:

	library(ggplot2)
	library(sqldf)
	# using the dataset 'raw' wich is a list of contractors by lat, long
	df <- sqldf("SELECT COUNT(*) AS num, LocLat, LocLong
	FROM raw GROUP BY LocLat, LocLong")
	g <- qplot(LocLong,LocLat, colour=num, size=log(num), data = df)
	png("india.png")
	print(g)
	dev.off()
