I have a question about doing some graphing with a custom script that I am
putting together.  What I will have is a table similar to the if_load table
with the cisco devices in devmon but in my table I am wanting to have a
column with links to the graphs so that I can click on them and have them
pull up the graphs instead of having them shown down at the bottom.  Can I
have hobbit create the rrd files via my script but just not put anything
into the hobbitgraph.cfg, so that no graphs show at the bottom of the page
and then use the rrd files to show my graphs?
If you use the beta (I also have a patch for 4.2) you can use the trends channel.  This allows you to send a message with bb to the hobbit server with information about the rrd files you want to create/update.  I use this to make rrd files without using the ncv module.
Next step is to change hobbitgraph so you can create a graph and include the correct link in your bb status message.

From the hobbit source:

 * Instead of a dedicated Hobbit channel for this, I decided to use the  * existing "data" message type. To use this, send a "data" message to  * hobbit formatted like this:
 • *    data $MACHINE.trends
 *    [filename.rrd]
 *    DS-definition1 VALUE2
 *    DS-definition2 VALUE2
 • * E.g. to create/update a custom RRD file "weather.rrd" with two  * GAUGE datasets "temp" and "wind", with current values "21" and  * "8" respectively, send this message:
 • *    [weather.rrd]
 *    DS:temp:GAUGE:600:0:U 21
 *    DS:wind:GAUGE:600:0:U 8
