Reconsider Knowledge Graph Bubble

[karafecho]

This issue is to suggest that we reconsider the purpose and design of the Knowledge Graph Bubble in the Question Builder result display. I have received many user questions about this. I think the main issue is that folks over-interpret the intent, sometimes thinking that we're displaying a visualization of some sort of enrichment, etc., when we're really just displaying a visualization of the relative frequency of a biomedical entity within the overall result set. The issue becomes even more confusing to users, I think, because we include nodes in the visualization that were specified in the query graph (i.e., found in every single answer subgraph).

I don't find the bubble all that useful myself - does anybody really like it?
