This is library to produce Chernoff Faces to display data. A face has ten attributes that are used to show variation in values.
This show the range from min to max on all of the values:
The more eccentric in the x axis it is the larger the value. Likewise larger values,
the more eccentric in the y axis for smaller values.
Eccentricity as with head shape.
Lower on the outside smaller values, higher on the inside larger.
More frowny smaller, more smiley larger.
The distance between eyes.
