Re: [Trisquel-users] vector plot software?

[legimet . calc]

I don't know much about this, but Sage is a very good mathematical software.  
It is a collection of various free software packages and a python interface.  
It is all free software, except it has a library called cephes under a  
questionable license. Luckily, this is only used on FreeBSD, not on  
GNU/Linux. (But I hope this is replaced in the future)
