Hi there skywalker,
While we only officially support Ubuntu 14.04, the visualiser tends to work just fine on Ubuntu 16.04.
The latest release v0.13.1 did include an upgrade of the electron framework used by the Visualizer, so it is possible there is a new issue. Have you successfully used other versions of the Visualizer (< v0.13.1) in the past?
Can you try opening the devtools using
Ctrl+Shift+i and then navigate to the "console" tab. If the console shows any errors, please report them back.
