This document is intended to be a helpful and reasonably full

introduction to the use of the ReportLab Graphics sub-package.

|
Starting with simple drawings and shapes, we will take you through the
|
||
|
slightly more complex reusable widgets all the way through to our
|
||
|
powerful and flexible chart library. You will see examples of using
|
||
|
reportlab/graphics to make bar charts, line charts, line plots, pie
|

|
charts... and a smiley face.
