Annotating individual flows lines with values

[pvphaneuf]

It would be nice to have a way of annotating individual flow lines, where one could annotate the value represented by a flow line for the sake of presentations.

For instance, annotating a value on each of the lines coming out of "bananas".

Could be very cluttered in the attached example, but simpler diagrams could benefit from the inclusion of the mouse-over values statically annotated on each flow.

Hi @pvphaneuf, thanks for the suggestion and sorry for the slow reply. I think this is a good idea, but it probably needs to be added as a feature to the underlying d3-sankey-diagram library first. I'll create an issue there to track this.

A similar feature is already present when one is watching the Sankey online or exported to svg, one could see the exact value of the flow hovering the cursor over it (the svg should be open from browser, tested with Chrome 68).

Thanks for clarifying, yes, mouse-over is already there -- but static labels are also useful in some cases.

This is nearly possible now -- see #74
