CharlesJ -

It might help if you describe the kind of chart you want (and the data upon
which it is based).

A Google search for "sales funnel chart" yields approx. 125,000 results.
Some examples seem to be quantitative (with what some chart gurus might
regard as unnecessary deception using length and areas), and some seem to be
merely line diagrams, not based on numerical data.
