TEXT/CAPTIONS
    The following GD::Graph options control placing text on the graph:
    title, x_label and y_label. GD::Graph for those and related options.
    In addition, this modules allows you to use the captionN option(s),
    to draw arbitrary strings on the graph. See below.

IMPLEMENTATION
    This module is implemented as a simple Apache mod_perl handler that
    generates and returns a png format graph (using Martien Verbruggen's
    GD::Graph module) based on the arguments passed in via a query
    string. It responds with the content-type "image/png" (or whatever
    is set via "PerlSetVar ImageType"), and sends a Expires: header of
    30 days (or whatever is set via "PerlSetVar Expires", or expires in
    the query string, in days) ahead.

    In addition, it keeps a server-side cache in the file system using
    DeWitt Clinton's File::Cache module, whose size can be specified via
    "PerlSetVar CacheSize" in bytes.

OPTIONS
