On my server I cannot reproduce this bug, or the others related to it (bugs
#4358, #4360, #4361). The graphics display correctly here.  The error message
you quoted below suggests there may be a problem on your server.  When webwork
creates this problem it creates a graphics file that it saves on your server. 
If the file is not created the graphics will not appear.  In my server the
graphics file file is created in the directory
/opt/webwork/webwork2/htdocs/tmp/ in the main webwork file tree.  The location
of this directory is defined in the webwork configuration file
webwork2/conf/site.conf in the line that defines  
"$webwork_htdocs_url" (without the quotes).  The directory webwork2/htdocs/tmp
may be located in a different place (it depends on the way your administrator
set up webwork) but the key thing is that it must be writeable by the server. 
If the server cannot write to this directory or if it can't read it then it
won't be able to create the necessary graphics to make this problem (or many
others) work.  Please ask your webwork administrator to check the permissions
on this directory; I suspect that may be the problem.  
I am going to close this bug with the "works for me" notation. But if checking
the directory permissions and checking the line in the config file doesn't cure
the problem then please reopen this bug or submit a new bug report referencing
this bug, #4359.  If you do I'll try to get someone to help who has deeper
knowledge of webwork's innards.
Thanks for including the error message, it is a very helpful clue.
