Incorporating Physics into Data Visualizations

Link to article Interesting article about data visualization, especially maps, that use fundamental physics/mechanics rules to solve problems with geometry, positioning, and make visualizations more interactive and engaging.

One example: using a library called Box2DWeb to incorporate collision detection and lifelike bubble movement into a world map of population size.

World Map - Population (with overlapping bubbles)

World Map - Population (using collision detection & animated movement)
