Indicator gauge dial to represent a value based on limits

Hello all,

I am trying to display an indicator gauge on my page (imagine something similar to a speedometer) which accepts parameters for its both its scale and the actual value to represent on the scale. Once passed the parameters, it would then draw a filled semi-circle up to the level of the actual value.

For e.g.

min value = 0
warning threshold value = 50
critical threshold value = 100
max value = 150
actual value = 120

So in the above e.g. this would show a filled semi-circle coloured green between 0-50, coloured amber between 50-100, and coloured red between 100-120. The remaining 30 (150 - 120) would be another colour or white space.

We do not have ASP installed so this would have to be simple html, javascript, vbscript, php, java applet etc.

Is this at all possible, and how could it be done?

Many thanks in advance.
