Details
The function determines the aspect ratio of the x- and y-axis to enforce
isosceles triangles. The aspect ratio will not be effected by defining
width and height in pdf() or other graphic devices.
Because the returned object is a ggplot2 graph, the overall appearence of
the graph can be edited by adding themes() to the plot.
