Unable to use inbuilt Visualisation in Zeppelin

Question

I am trying to use the inbuilt visualization of zeppelin when retrieving data from Cassandra keyspace using spark-cassandra connector:

import org.apache.spark.sql.cassandra.CassandraSQLContext
import org.apache.spark.sql.cassandra._
import org.apache.spark.sql
val csc=new CassandraSQLContext(sc)
import sqlContext.implicits._
val rdd1=csc.sql(“SELECT * from q_data.qr_ep_data limit 100”)
///rdd1.registerTempTable(“epdata”)
rdd1.registerTempTable(“epdata”)
%sql
SELECT * from q_data.qr_ep_data limit 10
Error::171: error: not found: value %
%sql

I am not able to use the %sql which throws me AN ERROR. Any help is much appreciated.
