This design pulls from demographic charts of Santa Clara County from the 2000 Census created by an elegant applet called Geocensus which works in conjunction with Google Earth.
The flower motif I created here was inspired by the mustard flower, a common rotation crop flower in the agricultural era and still visible through out Santa Clara in the few open fields and on trails. The bottom flower here is the White population demographics. The left flower is the Black population demographics. The top flower is the Hispanic population demographics and the right flower is Asian population demographics. These are all for Santa Clara County.
