Ambiguous example in README.md file

[jimka2001]

The README.md file specifies to use the JFGraphPlotter class, but does not indicate how bring it into scope. Do I need to add something to my build.sbt file? or does it require an import from the library already referenced in the build.sbt file?

libraryDependencies += "org.sameersingh.scalaplot" % "scalaplot" % "0.0.4"
