Cassandra Targett updated SOLR-13107:
-------------------------------------
Component/s: streaming expressions
> Math Expressions for custom Apache Zeppelin visualizations
> -----------------------------------------------------------
>
> Key: SOLR-13107
> URL: https://issues.apache.org/jira/browse/SOLR-13107
> Project: Solr
> Issue Type: New Feature
> Components: streaming expressions
> Reporter: Joel Bernstein
> Priority: Major
>
> This is an umbrella ticket for creating Math Expressions for custom Apache
> Zeppelin Visualizations
> Apache Zeppelin supports a growing number of visualizations out of the box
> which can all be accessed using the *zplot* Math Expression.
> Apache Zeppelin also has support for adding Angular code to support custom
> visualizations. There are a number of areas of interest:
> 1) More advanced map visualizations. Math Expressions can cluster lat/lon
> points, and draw convex hulls and enclosing circles around clusters. Apache
> Zeppelin mapping doesn't currently support drawing circles or polygons on a
> map. There is an interesting post that describes using google maps inside
> Zeppelin:
> [https://community.hortonworks.com/articles/75834/using-angular-within-apache-zeppelin-to-create-cus.html.]
> 2) Graph visualizations. The nodes expressions can flexibly walk a graph and
> export nodes and edges. It would be great to be able to visual a this graph
> in Zeppelin. Currently the Zeppelin network visualization seems to not be
> robust enough to work with larger networks so a custom custom visualization
> may be needed.
> 3) Clustering visualizations.
> 4) 3D Visualizations, particularly Multivariate Normal Distribution plotting.
