* GraphMaker - Used to create and ultimately output a gif image. |

|
|
* This class accepts a PlotData object in the constructor, yet has |
| 14 |
|
|
* the filename, size, etc. passed in a separate method - this is so |
| 15 |
|
|
* that the same PlotData can easily be used to create several graphs |
| 16 |
|
|
* of differing filenames, sizes, etc... |
