Re polygon drawing: some minimal effort will be required to provide something like 'snap to point' ability for drawing that closed loop (like CAD tools and Illustrator offer); one way to solve this is to use the same trick which can be used to 'test for hit' for clicking on a dot in a graph: there two systems see most use: one is using a voronoi overlay, which in your case I wouldn't advise. Manipulating and presenting geographic data can be very tricky, but building a map with a D3. This is the bare bones html page that includes the Bing Maps Control. If the vertices of the polygon are in counterclockwise order (assuming a coordinate system where the origin 0,0 is in the top-left corner), the returned area is positive; otherwise it is negative, or zero. For more, see Part 2 of The Toolmaker’s Guide. In the example below, d3 is used to select the circle with a class target and modify its stroke-width.
