Feature Proposal: create a generalised CHART Var definition that several ChartPlugins can re-use

Motivation

There are many many Chart generation tools mentioned here in Codev - lately, FlotForJQuery and WorkingWithGoogleCharts. I'd like to see a generalised TWiki VarCHART that can be used by all the Chart Plugins, so that users (and the developers) can try out a few of them, without needing to re-code topics for each.

ChartPlugin

Is specifically for creating charts from tables. It uses %CHART%, offering area, line, bar, scatter or combo charts using the GD graphics library.

GaugePlugin

only generates simple gauges

GnuPlotPlugin & PloticusPlugin

Require the user to know and use the scripting language of GnuPlot and Ploticus - giving massive power, but is not useful for most users without an added abstraction layer that thus proposal could offer.

Description and Documentation

Extending the syntax of ChartPlugin to allow more than data from tables - and for GeorgeTownRelease Named ResultSets...

eg. =%CHART{"1, 2,3, 4, 5, 6" size="200,140"}% ?
