This new release is now available with these features:
Support for plots made with generic command line tools via the shellscript backend.
Nice error handling when settings.DEBUG is off: exceptions are caught and displayed on the webpage instead of the plot (rather than throwing a 500 internal server error page).
R plots take on a value for r_code_filename of "class.name.R" by default, where class_name is the name of the subclass of dataplot.R.Plot (previously there was no default and you had to minimally specify r_code_filename).
These are the features I am planning to implement for release 0.5:
Examples for the shellscript backend.
Better example docs, including a website with HTML documentation.
OK to use in when installed in directories other than django/contrib.
