Scatter Diagrams

This scatter graph example visualize correlation between baby height and age.
"Human height is the distance from the bottom of the feet to the top of the head in a human body, standing erect. It is usually measured in centimetres when using the metric system, and feet and inches when using the imperial system. Human height has varied from under 60 centimetres (2 ft 0 in) to over 260 centimetres (8 ft 6 in). On average, males are taller than females. ...
Growth in stature, determined by its various factors, results from the lengthening of bones via cellular divisions chiefly regulated by somatotropin (human growth hormone (hGH)) secreted by the anterior pituitary gland. ...
The majority of linear growth occurs as growth of cartilage at the epiphysis (ends) of the long bones which gradually ossify to form hard bone. The legs compose approximately half of adult human height, and leg length is a somewhat sexually dimorphic trait. Some of this growth occurs after the growth spurt of the long bones has ceased or slowed. The majority of growth during growth spurts is of the long bones. Additionally, the variation in height between populations and across time is largely due to changes in leg length. The remainder of height consists of the cranium. Height is sexually dimorphic and statistically it is more or less normally distributed, but with heavy tails." [Human height. Wikipedia]
