Line graph in Pier

Pier Group,
For a small site, I have a list of the item costs and the day:

|! Date | ! Cost of Item 1 |! Cost of Item 2
| 2010-Feb-11 | $2.50 | $2.25
| 2010-Feb-10 | $2.45 | $2.23
| 2010-Feb-9 | $2.41 | $2.26
| 2010-Feb-8 | $2.52 | $2.24

My customer is perfectly happy entering the text each day, however he wants a line graph showing the rise and fall of the two items for the last few weeks. Is there anything in pier which will display this sort of data? Maybe something in Squeak/Pharo which would generate a morph, that can be turned into a jpg?

Thanks,
John

You might want to have a look at Google Chart:

You might want to use Raphael (on squeaksource) to generate the images.
