Searching for a Graphic plugin (gruff like) not using ImageM

Hi guys,
It’s my first post.
I’m searching for a graphical plugin like gruff or scruffy because I
found problems installing ImageMagick lib on the production server.
Also like gruff, the plugin must generate graphics in a suitable image
format (PNG for example) because I not only display the graphics on the
HTML page I also export them in a PDF format.
