Point out the correct statement.

The correct answer is D. All of the mentioned.

The gvisAnnotationChart function returns a list of class “gvis” and “list”. The gvisAreaChart function reads a data.frame and creates text output referring to the Google Visualization API.

Here is an example of how to use the gvisAnnotationChart function:

“`
library(gvis)

data(cars)

gvisAnnotationChart(cars, x = “speed”, y = “dist”, color = “cyl”, annotation = “This is an annotation”)
“`

This will create a line chart with an annotation that says “This is an annotation”.

Here is an example of how to use the gvisAreaChart function:

“`
library(gvis)

data(cars)

gvisAreaChart(cars, x = “speed”, y = “dist”, color = “cyl”)
“`

This will create an area chart with the data from the cars data frame.
