Yesterday I posted a map that used proportional symbols to visualize the home cities of Online News Association conference attendees. Today’s version uses great circles to map the routes attendees took to Boston (assuming they had direct flights, of course). Red lines represent more attendees from a location:
More than 1,000 people were on the attendee list for last weekend’s Online News Association convention in Boston, according to a list the organizers graciously released.
The data weren’t perfect. Only about 3 in 4 attendees listed their home cities. Of them, about 650 were from the United States.
As you can see in this map, the Northeast drew a heavy contingent, with Washington, D.C., New York City, and Boston leading the list. Wide swaths of the country, however, weren’t represented:
UPDATE (9/27): See a different (and perhaps more interesting) version.
