bitmap question

[dumdumsareyum]

I'm trying to make an interactive graph on a website. I am would like to create a bitmap...I imported system.drawing namespace and the help told me that in order to use the bitmap.line method I need to use the microsoft.spot namespace, but when I try to do "imports microsoft.SPOT" it doesn't recognize it. And then of course when I try to use mybitmap.line it tells me line is not a member of system.drawing.bitmap. Help please?
