Does simple charts

Can plot a single variable by itself or another single variable for a
range of chart types (line, spline, area, area spline, column, bar,
pie, scatter). Exports to printer, PNG, JPEG, PDF and SVG I believe.
Can include custom graph into rest of results which means it mixes with
tables & inferential tests.

Salstat is getting there.

Next is to allow charting of multiple variables.
