GraphModel: how to set a value on pre 3.30?
but when I try to run it on 3.28 I get this error:
AttributeError: 'GraphModel' object has no attribute 'iter_set'
Checking the doc it seems that this method was added only with version 3.30, but how can I add a value on version 3.28?
If I comment the missing liens the graphs are showing correctly but, of course, they are empty. Is there another way to add a value on version 3.28?
