+In the last post, I introduce the basics of Flink on Zeppelin and how to do
Streaming ETL. This is part-2 where I would talk about how to
+do streaming data visualization via Flink on Zeppelin and how to use flink UDF
in Zeppelin.
+
+# Streaming Data Visualization
+
+In Zeppelin, you can build a realtime streaming dashboard without writing any
line of javascript/html/css code.
+Overall Zeppelin supports 3 kinds of streaming data analytics:
+* Single
+* Update
+* Append
+
+### Single Mode
+Single mode is for the case when the result of sql statement is always one
row, such as the following example.
