New Template for GOJS library

Just had a look in one of the site -

Can your team work on developing a template like shown in link using GOJS.
I do not have any specific need for my project, but instead of standard bar chart using multiple bars, same if presented like this would be nice.

That seems like a simple modification to the itemTemplate used in Bar Charts

I think, it about constructing a petal for each value and then some layout needs to used.
Not sure what needs to be done. if possible from your team would be nice to showcase for you also.
