#209 not display "Visual subnet display"

[Anonymous]

Hi team
The application is excellent!

I have installed version 1.2 rev 1 in debian stable.
I do not see the functionality of "Visual display subnet" as in the demo online
I have reviewed other ticket but do not see a response or resolution.
I may say that I can do?
I should look in the settings?

ps:apologies for the ugly English
