Re: Simple 2d graphing in web page - where to begin

My Googling has let me down here - maybe because when it comes to Java
I don't really know which type I need! If someone could point me in
the right direction I'd appreciate it.

My requirement is simple: to display a 2-d graph within a web page
where the X and Y values are taken from a database (residing on the
server hosting the web pages). The GUI is to allow panning forwards
and backwards over time (the X values are 32-bit timestamps) and
zooming in and out. That's about it. It would be a bonus if there were
a time display of the cursor position as it is moved over the image.

Java noob question: what /type/ of Java would I need? I see there are
applets, servlets, beans and swing components... oh and Javascript
thrown in to the equation. I don't know where to begin!

I notice that IE warns about the security of some embedded components
but not others. Anyone know what makes the difference?

Is there any existing code that will do the 2-d graphing, as above,
that I could modify? Is there an existing package that will do all of
what I want? It seems a pretty basic requirement.
