So I have a subscription to gantter, I use the charts for schedules. I have noticed and looked at the Visualization tab, but it seems to have been in Beta for quite some time? What is the status of it? If I am paying a monthly subscription, I would like to see the value and the product evolving. 

We do apologize for the confusion. We have kept up the name Visualization (Beta), in this case we are referring to;
 beta represents the slope of the line through a regression of data points​.
