Labelling a Bubble Chart

Hi,

I would like to create a bubble chart from the following data:

Column A Label for data point
Column B Data for x-axis
Column C Data for y-axis
Column D Data to establish size of bubble

It's easy enough to draw the chart but how do I attached the labels to the points? I've got lots of charts to draw so I'd prefer not to have to label the points manually.

I am using Excel 2003

Thanks!
