Does GOJS library have arabic locale support?

Hi ,
We are using GoJS library for displaying the approval chain. But now we are also going to support arabic locale for the same feature. We tried style=“diection:rtl” but it didn’t work. If we try same with ltr orientation does not change. Can anyone guide us, how to support arabic locale for same feature ?

You need to set the HTML5 property dir="rtl" on the DIV, not a CSS style option, and you need to set textAlign: 'right' on your TextBlocks
