Gasoline Prices Over Time
Benjamin Williams - Music 220A Final Project

$4.25 $0.25

This is a combined visualization/sonification of the average price of gasoline sold through retail outlets from 1984-2011, in dollars per gallon. (Gaps in the data set were interpolated.) Time progression can be controlled using the buttons in the top left. Individual states can be included/excluded in the sonification by clicking them. A separate triangle tone will play for each state, as well as for a national average of the data: the intent is to be able to listen to the beating/etc between tones for subtle differences between states.
