Cassandra Targett commented on SOLR-13105:
------------------------------------------
I talked to Joel offline and we decided to re-do the branch.
I created a patch of my edits from the {{jira/solr-13105-toMerge}} branch and
then started over with a new branch {{jira/solr-13105-merge2}} based off the
{{visual-guide}} branch. I then merged {{master}} into the new branch, fixed a
couple very minor conflicts, then applied the patch. The result is basically
the same but in a much cleaner state (I think!).
If either of you would take a look at it before I make a PR, I would appreciate
it. I'm hoping that it's pretty close to ready to merge into master.

> Visualization is now a fundamental element of Solr Streaming Expressions and
> Math Expressions. This ticket will create a visual guide to Solr Math
> Expressions and Solr Streaming Expressions that includes *Apache Zeppelin*
> visualization examples.
> It will also cover using the JDBC expression to *analyze* and *visualize*
> results from any JDBC compliant data source.
> Intro from the guide:
> {code:java}
> Streaming Expressions exposes the capabilities of Solr Cloud as composable
> functions. These functions provide a system for searching, transforming,
> analyzing and visualizing data stored in Solr Cloud collections.
> At a high level there are four main capabilities that will be explored in the
> documentation:
> * Searching, sampling and aggregating results from Solr.
> * Transforming result sets after they are retrieved from Solr.
> * Analyzing and modeling result sets using probability and statistics and
> machine learning libraries.
> * Visualizing result sets, aggregations and statistical models of the data.
> {code}
>
> A few sample visualizations are attached to the ticket.
