Vegas fails to work when circe 0.9.3 is imported in Zeppelin

[dankolesnikov]

Vegas doesn't graph if the user imports circe 0.9.3 in Zeppelin.

To reproduce in Zeppelin, import the following in the spark interpreter and run a sample Vegas example:

• org.vegas-viz:vegas_2.11:0.3.11
• io.circe:circe-core_2.11:0.9.3

Throws exception:

java.lang.NoSuchMethodError: io.circe.Printer.copy(ZZLjava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)Lio/circe/Printer;

Attaching screenshots: Failure: circe 0.9.3 is imported

Success: no circe library is imported

I am currently working on the fix for this. vegas.spec. Spec singleton seems to be the one that requires changes. I'd like to connect with contributors/founder who wrote that code. My suggestion is to reduce the number of lines in vegas.spec. Spec by modularizing it. There are more than 2000 lines in a single file. Any feedback?

core/src/main/scala/vegas/spec/Spec.scala is automatically generated by argus package (c.f. https://github.com/vegas-viz/Vegas/issues/93 and here).

@oshikiri Updates on this:

• It looks that argus needs to be updated to 2.8 (not released yet)
• Assuming there is a breaking change in circe 0.7 - 0.9. Do you know of any?

I don't know about it. Could you send a pull request and check using travis-ci?
