API patch 65 makes some minor improvements to the visualization feature, summarized below:


1) GRP-2246: Visualization: tune group count query for better performance in MySQL


When including group counts, a query was used against a view, which itself relied on another view. A user reported this caused performance issues with a MariaDB database. After rewriting the query to use the primary view directly, performance improved by a factor of about 30.


2) GRP-2191: if a composite is used in visualization, it should show both factors and overall (if allowed)


Due to the way visualization traced paths of parents and children recursively, when starting from a composite factor the visualization graph could miss the other composite factor. This fix treats composites as a special case, querying the children to a single level,

when it would otherwise skip child querying.
