Modeling Disease Spread
What looks like a Native American dream catcher is really a network of social interactions within a community. The red dots along the inner and outer circles represent people, while the different colored lines represent direct contact between them. All connections originate from four individuals near the center of the graph. Modeling social networks can help researchers understand how diseases spread.
