Any fan of info-maps (as I surely am) will find one of the
newest creations fascinating.
Made by Harvard Ph.D. student
Robert Manduca, this intricately designed visualization maps nearly every job
in America, one dot per job. According to the Washington Post’s “Wongblog,” his
project draws on Census data
reported by employers
.

As a result, this
U.S. map covers about 96 percent of all private-sector jobs, including
part-time workers, as well as many federal and state jobs. But the data
excludes the military and federal agencies related to national security.
The dots are also color-coded, with
manufacturing and trade jobs shown in red; professional services jobs in blue;
healthcare, education and government in green; and retail, hospitality and
service-sector jobs in yellow.

You can link to the map here and do some
maneuvering. To hover over parts of Michigan, zoom out, move your cursor over
to our state and then zoom in to maximum 
effect.
