The default height of plot was not providing enough clarity for the first plot shown here:

To do that I increased the height of the plot like so:

Which resulted in the 1st plot overlapping with the second:

@nleiby In our current version we have Visualization option in which you can set the height which works. Now someone may want to set the Frame for the image different from the image size, which they can currently do using graph layout height (as above) and the visualization option. on the other hand having two places to change the height may be confusing.
we can.

1. Leave it as is, allowing customizability
2. code in behavior for graph layout height
   a. Cannot be larger than visualization option height
   b. Sets the visualization option height (and has precedence)
   c. Does not do anything and we get rid of it from our schema
