Visualizes genomic breakpoints resulting from copy-number aberrations (amplifications and deletions) and chromosomal rearrangements (translocations and inversions).

Creates a bar plot that shows number of breakpoints in each chromosome (grouped by breakpoint type) and for each chromosome a figure with a scatter plot and a histogram of the locations of the breakpoints.

WARNING: Loads the whole data into memory twice, so beware of using big data.

Also note that this is an early version, and assumes specific columns for the inputs.
