Introduction

Near south pole, there are three kinds of penguins based on a research by Dr Kristen Gorman. They are * Chinstrap, * Adelie, and * Gentoo. Source: click here link

Chinstrap

The chinstrap penguin is named after the thin black band that extends from ear to ear around the bottom of his chin. The penguin also differentiates himself from other penguins by having a white face. Chinstrap penguins breed in large colonies, sometimes as large as 100,000. They can be found throughout the Antarctic peninsula and its neighboring islands. The species survives almost entirely from a diet of krill, which is plentiful in Antarctic waters. Chinstrap penguins spend winters in the open ocean north of the Antarctic pack ice.

Adelie

The Adelie penguin lives all along the Antarctic coast and its outlying islands. Like many penguin species, the Adelie variety lives in large colonies during the spring breeding season, which begins in October. Adelie build small nests with small rocks, sometimes stealing rocks from each other. In addition to krill, the Adelie penguins dine on fish and squid. They are capable of diving more than 500 feet in search of prey.

Gentoo

Gentoo penguins live along the Antarctic peninsula and its islands. They inhabit the coastal areas, avoiding areas with sea ice. The third largest penguin, gentoos belong to a group known as “brush-tail” penguins, so called because of their long tail feathers. Males and females take turns guarding the nests while the others venture out to feed. Gentoos are highly territorial, fiercely defending the small area immediately surround their nests. They are not deep divers and primarily feed in shallow waters.

Setting up an environment

Following R code is for preparing visualization the size by displaying their body mass (in gram) and flipper length (mm). First, R environment setting is done by loading the required packages like tidyverse, ggplot2, and palmerpenguins in R.

install.packages("tidyverse", repos = "http://cran.us.r-project.org")
install.packages("ggplot2", repos = "http://cran.us.r-project.org")
install.packages("palmerpenguins", repos = "http://cran.us.r-project.org")
library(tidyverse)
library(ggplot2)
library(palmerpenguins)

Visualization

You can embed the visualization with the R querry as displayed below:

ggplot(data=penguins)+
  geom_point(mapping=aes(x=flipper_length_mm,y=body_mass_g,color=species))+
  labs(title = "Palmer Penguins: Body Mass vs. Flipper Length", subtitle = "Sample of Three Penguin Species",
       caption = "Data collected by Dr. Kristen Gorman")+
  annotate("text",x=220,y=4000,label="The Gentoos are the largest",color="blue",fontface="bold",size=4.5,angle=30)
