Computer or graphing calculators

[spacecadet11]

Hello. I would like to know if my 'computer' at home has the ability to become a 'graphing calculator' of sorts?

I read some where that there exists a 'computer grapher'........program or something that would do that job.

Thanks for any and all responses
Bye
