A relevancy bar generator.

Originally created for searchforcode.com, but free to use for whatever you like. See the included screenshot for samples of how to use it, and please vote!

cool!

While I STRONGLY recommend against 
using Hexidecimal Hash values for the 
colors, it is still a good code. 5 
globes.

May be you could add default 
values:
if(!isset($width)) 
$width=70;
to shorten the url in 
some cases

Very cool and useful.  It would be nice 
though, if your max is set at 100 or 
something to NOT have 100 little bars.  
I think I can fix that though.
Well 
done!

If you want to have your max a large 
number like 100, you could always 
divide all your numbers by a common 
number to reduce the number of bars.  
For example, if you divided all your 
numbers by 100 and set the maximum to 
1, you would see no bars at all.  If 
you were to divide all your numbers by 
5 and set your max to 20, you would see 
bars every 20 integers.  It's all in 
manipulating the multipliers.  If this 
makes no sense to you, the code is 
simple enough to change to do what you 
like...
