It was also more complicated than I hoped, wanting to use Vega-Lite as a better Excel to explore this data, and not to write my own chart-app if that makes sense (different purpose). Default value: This will be determined by the following rules: If a view's autosize type is "fit" or its x-channel has a continuous scale, the width will be the value of config.view.width. I believe you can use Vega-Lite API to implement a hover effect. - Data values for a temporal field can be either a date-time string (e.g., "2015-03-07 12:32:17", "17:01", "2015-03-16".
