Feature request: Mobile - tap label to show difference

[harry643]

On mobile, I would like to tap the node label to see the difference between a node and its onward nodes.

I can do this on desktop by hovering over the node label:

I tried to find where this was in code to do it myself but I only got as far as finding 'nodeTooltip'. I couldn't find where this was being applied as alt text.

Hey, current behavior is using a vanilla title element inside the SVG (fyi: this is the code part:

sankeydiagram.net/src/js/d3-sankey-diagram/src/node.js

Line 63 in b15dd6a

.text(tooltipText);

)

Sadly (most) mobile browsers do not support rendering that on long-press or similar :( We would need to add some supporting JS that either adds some fallback display-logic for mobile users, or add that custom display-logic for all users if there isn't some simple way/hack for making the normal title tag visible on mobile
