Black_cherry_tree_histogram.svg‎ (SVG file, nominally 216 × 216 pixels, file size: 4 KB)

This is a file from the Wikimedia Commons. The description on its description page there is shown below.Commons is a freely licensed media file repository. You can help.

Based on the following R code:

pdf("Black_cherry_tree_histogram.pdf", 3, 3, pointsize=10)
par(mgp=c(1.9,.7,0), mar=c(3,3,2,1), lend=1, ljoin=1, lmitre=4)

hist(trees$Height, col="burlywood",
     xlab="Height (feet)",
     main="Heights of Black Cherry Trees")

dev.off()

The figure was then edited slightly in Adobe Illustrator, then saved in SVG format.

Information regarding the dataset can be obtained from the R prompt:
