splendid use of the symlog scale!

Thanks!

seconding @Fil! this is really nice, i'd struggled w/ that, symlog's a great idea

Thanks!

This is great. Would you be interested in adding this chart to the examples at https://vega.github.io/vega-lite/examples/?

Sure!

Do you think it would be possible to make "states to be called" take into account the dates? So that Pennsylvania would still be visible a few days ago, for example

Good call. It should now show which ones are not called on the date selected in the slider.
