I would expect displaying and exporting the descendants of Wm in a straight-line to you in the Descendants Chart would give the exact same dataset - unless it doesn't show multiple lines of descent (ie cousin marriages).
But, whatever floats your boat.
".... display visually"
Have you tried the three reports I mentioned?? They should give you three alternatives.
The only wrinkle might be whether the charts (2 and 3) can handle multiple lines of descent. The Outline Descendant Report CAN handle multiple lines of descent (ie evidencing cousin marriages between ancestors).
All three will show at least one line of descent directly from Wm to you; and the ODR will show AlL lines.
