Differences From Artifact [7a2dc3b4a6]:

• File src/graph.js — part of check-in [a27ca27f1d] at 2019-05-18 18:57:40 on branch tooltips — Improvements to branch linkage from the tooltip. Branch linkage now works even from a file history graph. And the source check-in is always highlighted in the linked timeline. (user: drh size: 20954)

To Artifact [11b8e8cb4e]:

• File src/graph.js — part of check-in [8b8eaad864] at 2019-05-20 08:14:00 on branch tooltip-experiments — Make the "click to show tooltip" action more "discoverable" with a changing mouse cursor, similar to the timeline nodes. This example uses the "pointer" cursor, but the "help" cursor may also be an option. (user: florian size: 21162)
