To save a visualization created using the R package googleVis to a PNG file, you can use the png() function to open a PNG device and then use the print() function to print the visualization to the device. Here’s how you can do it:
library(googleVis)
# Create a googleVis chart
data <- data.frame(country=c("US", "GB", "BR"), val=c(100, 200, 300))
chart <- gvisPieChart(data, "Country", "Val")
# Open a PNG device
png("chart.png")
# Print the chart to the device
print(chart)
# Close the PNG device
dev.off()
This will create a PNG file named “chart.png” containing the visualization created with googleVis. You can specify the desired file path and name inside the png() function.
