Gauge Visualization Widget

Hi Developers,

I wanna have multiple gauges in web application to show the status of some industrial packages. I use the VaadinVisualization but I don’t know how to change the value without refreshing the page. The Google Chart Tools do that very nicely without refreshing the page by showing the motion of changing the indicator
. It’s so nice.

When I use the Google Chart Tools I faced with the error : (TypeError): $ is undefined

How can I do that?

I wanna set new value of gauge in every 1 minute without refreshing the page.
