betodealmeida opened a new pull request #5642: Filter out null locations by 
default
URL: https://github.com/apache/incubator-superset/pull/5642

be filtered out by default. Currently, they are shown as `0, 0`, which is 
confusing.
   
   Here's how the `flights` dataset currently looks like — note all the arcs 
with an edge at the Equator/Greenwich:

   When we toggle "Ignore null locations" they are removed:
