dformat returns the string representation of a float64 according to the datafmt flag value. if there is no fractional portion of the float64, override

vmap maps one range into another

xmlesc escapes XML

Getdata reads input from a Reader, either tab-separated or CSV

Write performs chart I/O

mean computes the arithmetic mean of a set of data

GenerateChart makes charts according to the orientation: horizontal bar or line, bar, dot, or donut volume charts

arclabel labels the data items

cpolar converts polar to Cartesion coordinates, compensating for the canvas aspect ratio

datasum computes the sum of the chart data

parsecondition parses the expression low,high,color. For example "0,10,red" means color the data red if the value is between 0 and 10.

commaf returns a string from a floating point value using commas to separate thousands. (from https://github.com/dustin/go-humanize/blob/master/comma.

data split divides a data set into two sections
