Are you looking for existing graphs and charts or do you want the raw market data?
You can get market information directly from MtGox in JSON format via their web API. There is some documentation at https://en.bitcoin.it/wiki/MtGox/API/HTTP/v1.
In your case, it sounds like you want the depth information:
https://mtgox.com/api/1/BTCUSD/depth
This information is up to date and should reflect the current state of the market. There is also more advanced functionality to place orders, get a continous stream of market updates, etc.
Unless you're writing code yourself you should probably look for some existing programs that use these data feeds. I write my own so I don't know what people tend to use.
