Description

What is your suggestion?

I'm wondering if it would be helpful if .interactive() did more by default. I'm primarily thinking about adding a tooltip (of the plotted encodings), and an interactive legend (based on opacity). There should of course be some way to turn these on/off, so that they don't interfere with manually set up bindings (maybe chart.interactive(legend=False).

Have you considered any alternative solutions?

Research direction
Study the current `.interactive()` implementation in Altair's source code, specifically how it adds bindings. Understand the Vega Lite tooltip and interactive legend specifications. Propose a design that adds tooltips and opacity based legends by default with toggles.
