Commodity Prices: A Visual Approach

Trading commodities -- oil, coffee, gold, corn, wheat -- is complex.  At any one time, several futures contracts with different delivery dates are trading for each commodity on the different commodities exchanges.  No single price for a commodity can be quoted.  Traders must track this stream of prices.  This is both a data manipulation challenge and an information processing challenge.  Can visualizations help the commodities trader?  This project attempts to make such pricing information digestible.
