Issues with Visualizer plugin

I’ve created a page on my organization’s WordPress site and used the Visualizer plugin to create a number of graphs and charts. The first issue I encountered was that I was unable to edit a chart once it had been created because of a JavaScript error. The edit pop-up simply came up empty each time I tried to edit. With the help of ThemeIsle support I managed to boil it down to an incompatibility with the Fruitful theme. It works fine with all other themes tested.

I’ve proceeded to put the site in Maintenance mode and changed to a different theme every time I’ve had to edit the charts, which has worked okay so far although it is far from ideal.

The second, and more important, issue is that once I published the page and tried it out in different browsers, all the charts are blinking on Safari for Mac and on Chrome for iPhone. For some strange reason it is working fine in Chrome for Mac and Safari for iPhone.

Does anyone have any ideas on how to solve this?
