[Editor’s note: The interactive Google Maps mashup in Flash AS3 from the New York times shows vector overlay of choropleth mapping by census tract and at the street level via dot distribution. As the user zooms in, the dots are revealed, as is a street map. At all levels the census tract summary statistics are available with a mouse over. Zooms are preset for some areas, and the user can type in their own address to zoom to that area. Multiple years add time dimension. Spatial brushing on the map is accomplished by outlining the geography’s stroke, not changing the fill color. Thanks Laris!]
