The correct answer is D. all of the mentioned.
GoogleVis, googleChart, and googleDataVis are all R interfaces to Google Charts. They allow you to create interactive charts and graphs from your R data.
GoogleVis is a package that provides a high-level interface to Google Charts. It is easy to use and can be used to create a variety of charts and graphs.
googleChart is a package that provides a low-level interface to Google Charts. It is more powerful than GoogleVis, but it is also more difficult to use.
googleDataVis is a package that provides a data-driven interface to Google Charts. It is designed for use with large datasets and can be used to create interactive charts and graphs that are updated in real time.
Here is an example of how to create a chart using GoogleVis:
“`
library(googleVis)
Create a data frame with some data
df <- data.frame(x = rnorm(100), y = rnorm(100))
Create a scatter plot
plot(df$x, df$y, type = “p”)
Add a title
title(“A Scatter Plot”)
Add a subtitle
subtitle(“Created with GoogleVis”)
Add a legend
legend(“topright”, legend = c(“x”, “y”), pch = 16, col = c(“red”, “blue”))
Save the chart
savePlot(“my_chart.png”)
