In the logic example, edit parts listen to their model with a
PropertyChangeListener. refreshVisuals() is called from the propertyChange()
method and the view is refreshed in refreshVisuals().

Iam able to change the model and figure as you described.
But the image/label is overlapping with or without overriding
propertyChange method.

What do you mean by "overlapping"?

Initially i have set figure with new Label("initial name").
Iam changing both figure and model dynammically by calling
figure.setImage(new Label("display name"))
model.setName("newname")

when i do this figure is getting set with "new name" but the "initial
name" retaining as it is.

or is it just enough to change the model and fire event programatically to
refresh the visuals.

Always change only the model, and the figure will be refreshed to reflect
the model's contents.
This point is stressed in an upcoming article on getting started with GEF.

yes i did get a reference to the model in EditPart and modified the same.
In order to reflect the changes i have overridden method called
propertyChange which calls refreshVisuals, but the view/figure is not
getting updated.

pls let me know whether the step followed are correct or not.

You shouldn't edit your model in your edit parts. You should generate commands
via edit policies and execute the commands on the command stack. The commands
will modify the model and then your model should notify listeners of a property
change event. When propertyChange() is called, call refreshVisuals().
