<h3 dir="auto">Superset version</h3>
<p dir="auto">0.19.0</p>
<h3 dir="auto">Expected results</h3>
<p dir="auto">Want the ability to filter the dashboard with an array rather than string values only. Example:<br>

<h3 dir="auto">Actual results</h3>
<p dir="auto">Only able to filter based on set string values<br>

<h3 dir="auto">Steps to reproduce</h3>
<p dir="auto">As shown above</p>
<p dir="auto">It is difficult to find any meaningful information about the deckgl charts.</p>
<p dir="auto">Would it please be possible to add at least rudimentary documentation providing a brief overview of the accepted geospatial formats (e.g. GeoJSON) and any requirements such as coordinate reference system (e.g. epsg 4326?), geometry types (e.g. do Multipolygons work or only Polygons?) etc.</p>
<p dir="auto">Thanks.</p>
