Review comment:
To me, `null` means users specifically choose an empty value for the
filter. `undefined` is more like the "data not yet available" default.
In `FilterBox`, the `defaultValue` is also `undefined`, not `null`:

Since there is no way to set a default filter for table charts, using
`undefined` to indicate "not set" seems more appropriate to me.
