Graduated Symbols


Neat graduated circle map projecting US pop in 2050 with graduated circles emphasizing major urban centers: http://www.america2050.org/images/2050_Map_Megaregions_Influence_150.png

Very nice interactive map from NYTimes of Immigration data from 1880. Has both choropleth and graduated circle variations: http://www.nytimes.com/interactive/2009/03/10/us/20090310-immigration-explore...

Visualizing the US power grid (note the isoline version as well): http://www.npr.org/2009/04/24/110997398/visualizing-the-u-s-electric-grid

World population: Not the snazziest symbols, but I bet you like the 2.5D aspect: http://thematicmapping.org/api/symbolimage.php

And to be topical, here are two Ebola maps with graduated symbols: http://www.washingtonpost.com/blogs/wonkblog/wp/2014/10/15/understanding-the-ebola-epidemic-in-2-charts-and-2-maps/
