Feature request: allow displaying weight values on links

[frank-yifei-wang]

Please support displaying weight values on links -- the soul of Sankey diagrams is to show the linkage between nodes and the weight (how much is transferring between nodes) —

Yes there is a Data link labels option, however it adds not only weight values but also all node names, so once turned on the visual becomes very cluttered. Also a bug here is although data field Amount is set to Currency format with 2 decimal places, the shown values in data link labels are still not like $1,630.00 —

A suggestion is to merge Data label and Data link labels into a new Data label option, and add toggle controls under it to allow the users to individually turn on/off Source/Destination/Weight labels. This way turning on Weight only achieves what is been asked for in the caption (many users will love it...), while turning on all three is equivalent to turning on today's Data link labels (viable only for uncluttered simple/small charts).

Thank you for considering this feature request and fixing the mentioned bug.
