Considerations on handling Boxplot when computed height is non-positive #1628
Description
Boxplot height calculated on front-end here.
This results in a mark that cannot be interacted with when d.boxLower - d.boxUpper <= 0 (which happens when all values are the same).
Does it make sense to implement a minimum height that enables interaction e.g. on_element_click and on_hover for this edge case?
