Vegas install issue in Zeppelin

[rpwang]

Hey,
Zeppelin works fine here ( I am using the latest version) but when I installed Vegas using:

./bin/install-interpreter.sh --name vegas --artifact org.vegas-viz:vegas_2.11:0.3.11

and use the example code I ran into a java runtime error. What did I miss?

%spark
import vegas._
import vegas.render.WindowRenderer._

val plot = Vegas("Country Pop").
withData(
Seq(
Map("country" -> "USA", "population" -> 314),
Map("country" -> "UK", "population" -> 64),
Map("country" -> "DK", "population" -> 80)
)
).
encodeX("country", Nom).
encodeY("population", Quant).
mark(Bar)

plot.show

result:
