[AccessD] Create a BarGram from data

Hi Folks,
I have to do something which I have never done before and would really
appreciate your help and feedback.
The charity I support is doing a charity walk and we need to have a guage
generated showing progress (something like you see on the side of a church
to show how the restoration fund for the new church roof is progressing).

My Access tables will capture the MilesWalked v MilesTarget and FundsRaised
v FundsTarget.

Somehow I have to generate a "picture" of each from these values which I can
then drop onto the web site as two graphics.

I will need to "scale" the MilesWalked to the MilesTarget and create the
"picture" from that.

And then do the same with the funds.  A sort of Progress Bar thingie but for
the web site.

All input is captured into an MDB, but how on earth do I do the rest?

Any help would be most appreciated.  Evan a start point.

Thanks
Max
