   @feng-tao and @astahlman I think I have the a solution. I created a fall 
back on the graph view on the last known graph in de database. With this also 
comes a warning to the user that the view might be incorrect. Should we maybe 
add a link to some docs?
   
   On changes that predates this change the user will see this if there is not 
a new DagRun yet:

   In case there is a DagRun with this changes the the old DagRun will show 
like this:
