Please add data attributes data-from-id and data-to-id to g class='edgeLabel' svg / make it clickable in flowchart

[d2a-raudenaerde]

Hi,

I'm trying to make an interactive flowchart, where my customers can click on the edges to filter data based on that transition.

However, there is no link between the rendered svg and the edge labels (there is info for the paths, in the id attribute, but paths are hard to click on, and the label overlaps the paths, so users can't click there).

Please add one (or two) data attibutes, preferably: data-from-id and data-to-id or similar with the id of the nodes (the nodes data-id).

For an example flowchart that I'd like to have:

Should be somethin along these lines:

edgeG.attr('data-from-id', edge.sourceId);
edgeG.attr('data-to-id', edge.targetId);
