    different formats (lines, bars, etc). You can also use the dataset base
    class, "Chart::OFC::Dataset", when creating a pie chart.

    The dataset classes provided are:

    *   Chart::OFC::Dataset

        The base class for all datasets. It has no formatting, and can only
        be used with pie charts.

    *   Chart::OFC::Dataset::Bar

    *   Chart::OFC::Dataset::FadeBar

    *   Chart::OFC::Dataset::OutlinedBar

    *   Chart::OFC::Dataset::GlassBar

    *   Chart::OFC::Dataset::3DBar

    *   Chart::OFC::Dataset::SketchBar

        Formats your data as a set of bars. There are many different styles
        of bars.

    *   Chart::OFC::Dataset::Line

    *   Chart::OFC::Dataset::LineWithDots

        Formats your data as a line, with optional dots marking each value.

    *   Chart::OFC::Dataset::Area

        Like a line with dots, but this dataset also fills in the area
        between the line and the X axis with a color.

   Axes and Axis Labels
    When you are creating a non-pie chart, you will want to create an X and
    Y axis for the chart. These are represented by the "Chart::OFC::XAxis"
    and "Chart::OFC::YAxis" classes.

    These classes in turn can take a "Chart::OFC::AxisLabel" class to define
    the label for the entire label.

   Grid Charts
    A grid chart can contain any number of datasets, in any combination of
    bars and lines.

   Pie Charts
    A pie chart displays a single dataset, with each value as a pie slice.

  Colors
    Many attributes in different classes expect a color. Colors can be
    provided as an RGB hex string with a leading "#" symbol, or as color
    names. Names are translated into RGB by use of the
    "Graphics::ColorNames" module, using the "X" scheme. See that module's
    docs for more details.

  Opacity
    Several classes accept an opacity value for an attribute. This should be
    a value from 0 (completely transparent) to 100 (completely opaque).

ATTRIBUTES
    This class has a number of attributes which may be passed to the "new()"
    method.

  title
    This is shown as the title of the chart.

    This attribute is optional.

  title_style
    This should be a chunk of CSS specifying attributes that apply to text,
    such as "font-size", "color", etc.

    This defaults to the string "font-size: 25px". Without a default
    specifying a sane size, the default size OFC uses seems to 1px or so.

  tool_tip
    This defines how tool tips are generated for data points. It uses a
    simple templating language. See
    http://teethgrinder.co.uk/open-flash-chart/gallery-tool-tip.php for
    details.

    This attribute is optional.

  bg_color
    The background color for the chart and surrounding text.

    This attribute is optional.

METHODS
    All of the above named may be accessed as read-only accessors on an
    object.

    This class also provide several additional methods.

  as_ofc_data
    Returns a textual representation of the chart suitable for delivering to
    OFC.

ROLES
    This class does the "Chart::OFC::Role::OFCDataLines" role.

TODO
    This distribution does not yet support all of the features of OFC.

    There are a few items left to do, notably grid charts with 2 Y axes, and
    background images.

    It would also be nice to generate embeddable Javascript for populating
    charts, since this lets you create a chart without making an additional
    server request for the data.

    Patches are welcome.
