Have you tried to import hammerjs? Or this zoom library?

This library allows you to listen touch events. Maybe you can observe zoom in and zoom out event and move brushes sending a signal to vega.

I hope to helped you!

Not yet. Can I listen to the events from a Vega spec?

[josesaranda]

I don't think so. I mean that you can create a listener for touch interactions events with the screen an then set a signal for vega to update the brush.
