-* '''Example 2''': Geographic variation of Ozone pollution: This plot shows a bubble for each of the California locations where monthly measurements of Ozone pollution were recorded between 1980-2006. The size of the bubbles reflect the maximum annual pollution and the bubble color indicates the average annual ozone pollution -- hot-colors represent high and cool-colors represent low ozone pollution levels, respectively.

 Using [http://socr.ucla.edu/SOCR_MotionCharts/ SOCR Motion Charts], we can demonstrate the temporal (time) effect on the Ozone in California. The two examples below show 2 alternative views to render part of these data. The [[SOCR_MotionCharts_CAOzoneData | SOCR Ozone Motion Charts Activity]] provides a more detailed case study based on these data.
-* '''Example 1''': Winter (January) and Summer (August) Ozone levels (ppm): Notice the annualized increase of the ozone pollution with time (increase of the proportion of hot-colored bubbles with time). Also observe that the ozone polution seems be a more geographically spread out phenomenon in the 2000's, compared to the 1980's -- most of the bubbles cluster together in later years, whereas there were wider geographic-driven fluctuations in the ozone particles in the earlier years.
