Info needed for 3B2 software

[vijay hemraj jadhwani]

I have 3B2/300 and 3B2/310
running Unix System V, 2.0. I have applications that run on it. I am interested
in introducing graphics in those applications. I would need facilities that
provide graphics support(in OS or as separate utilities). My needs are
restricted to things like bar charts, pie-charts, line-charts and windows.
Can anyone tell me whether graphics is available for 3B2s from ATT or other
vendors. 
Thanks in advance for any info.
