Visualizer
From fmepedia
Visualizer is a Workbench Transformer.

Description
The Visualizer allows you to view the internal FME FFS data as it is being handled by FME at that particular moment. FME will open the Universal Viewer [[1] (http://www.fmepedia.com/index.php/FME_Applications_-_Usage_and_Known_Issues#Universal_Viewer)] for this and load the data in a new view. If you have multiple Visualizers in the Workbench, FME will create a new Viewer dataset for every Visualizer. The name of the dataset corresponds with the name you have given to the Visualizer transformer.
This is a very useful tool for debugging workspaces. Keep in mind though that you are viewing the internal FME data, which may not be the same as the data eventually written to your output dataset, as the FME data does not suffer from any format-imposed restrictions.
Example
In this example features are generated and output using the different Visualizer settings. The idea is to show:
- How a group-by setting colours features of the same attribute value with the same colour
- How the names of the Visualizers affects the display order of features
- How to override line colour and area fill

The order of features, from the top down, is...
- Group-by Setting
- Display Order (ordered by Visualizer name)
- Line Color and Area Fill Override
- Line Color Override
