Using https://github.com/vega/vega-tooltip. Depends on #1.

Haven't looked closely enough at the underlying code yet, but perhaps https://beta.observablehq.com/@freedmand/vegalite-tooltip could help.

It doesn't seem to work as expected though, as the tooltip remains the same regardless of which part of the timeline the mouse hovers over.

The tooltips can't work on pure line or area charts because these are only a single mark. You can add an overlay with points to make it work. See https://github.com/vega/vega-tooltip/issues/120

We are working on a tooltip specification for Vega and Vega-Lite. Until then, I recommend not to make any changes to this library and just use the Vega and Vega-Lite tooltip channels.
