Hi,
I am trying to run the example:
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
But I get a:
Exception in thread "main" java.lang.NoClassDefFoundError: cats/functor/Contravariant

In my build.sbt
:
import Dependencies._
lazy val commonSettings = Seq(
organization := "fr.xxxxxxxxx",
version := "0.1.0-SNAPSHOT",
scalaVersion := "2.11.4",
libraryDependencies += scalaTest % Test
)
lazy val root = (project in file(".")).
settings(
commonSettings,
name := "xxxxxxxxxxxx",
libraryDependencies ++= vegas
)
In my Dependencies.scala
:
val vegasVersion = "0.3.11"
lazy val vegas = Seq(
"org.vegas-viz" %% "vegas" % vegasVersion
)
What am I doing wrong ?
Thanks in advance for any help.

Just bumped into this. Looks like a conflict of the versions of the "cats" library used with some of the other deps

Having the similar issue, using scala 2.11.12, can't see enough usage or issues around here.
