Could you all please let me know more in details about GoJS license

Hello all,

I’am a last year student in Thailand.
and I need to complete some project in order to finish my program.

interested in GoJS and now i’m considering it to be part of my project
my project is wireless signal simulator by drawing 2d floorplane on HTML , locate AP on floorplan and simulate wireless signal … how far can wifi signal go , and bla bla

but I’m really concern about software license
as a student I’m afraid that I can’t afford it

what can I do or could anyone advise me some another solutions?
Thank you
