D3 vs Google Data Projection

README.md

This example shows the county boundaries for Illinois. In red we see the google.maps.Data() layer in blue a D3.geo.path() with mercator projection.

The google data layer is an object which displays in the same canvas as any google overlay (polygons, markers, polylines, etc) while the D3.geo.path() shows up in an SVG container I overlap on top of the google container.
