A chart is simple a series of numbers rendered as a graph.
PowerPoint simplifies the process of inserting an Excel chart by actually embedding it as an object in the slide.
An embedded object is an object that maintains a direct connection to its original program.
After you insert an embedded object you can easily edit it by double clicking it.
This opens up the program in which it was originally created.
Embedding objects into your presentations will increase the file size.
An alternative to embedding the object is to link it.
The presentation only stores an image of the original chart and contains a link back to the original workbook.
