\arguments{
\item{data}{a \code{\link{data.frame}} to be displayed as a gauge}
\item{labelvar}{name of the character column which contains the category
labels for the slice labels.}
\item{numvar}{a vector of column names of the numerical variables of the
slice values.}

\Sexpr[results=rd]{paste(readLines(file.path(".", "inst",

\item{chartid}{character. If missing (default) a random chart id will be
generated based on chart type and \code{\link{tempfile}}}
}
\value{
\Sexpr[results=rd]{paste(gvisChartName)} returns list
of \code{\link{class}}

}
\description{
The gvisGauge function reads a data.frame and creates text output referring
to the Google Visualisation API, which can be included into a web page, or
as a stand-alone page. The actual chart is rendered by the web browser using
SVG or VML.
}
\examples{
## Please note that by default the googleVis plot command
## will open a browser window and requires an internet
## connection to display the visualisation.
Gauge1 <- gvisGauge(CityPopularity, options=list(min=0, max=800, greenFrom=500,
greenTo=800, yellowFrom=300, yellowTo=500,
redFrom=0, redTo=300))
plot(Gauge1)
