An experiment: what does it look like when we use jsonschema2pojo to generate Java Classes that map to the vega-lite spec?
/**
* Schema for Vega-lite specification

*/
@JsonInclude(JsonInclude.Include.NON_NULL)
@Generated("org.jsonschema2pojo")
@JsonPropertyOrder({
"data",
"marktype",
"encoding",
"filter",
"config"
})
public class VegaLite {
/**

*/
@JsonProperty("data")
private Data data;
/**
*
* (Required)
*
*/
@JsonProperty("marktype")
private VegaLite.Marktype marktype;
/**

*/
@JsonProperty("encoding")
private Encoding encoding;
@JsonProperty("filter")
private List<Filter> filter = new ArrayList<Filter>();
@JsonProperty("config")
private Config config;This would be a nice starting point for Java/Scala/Clojure libraries to wrap logic creating vega-lite charts, then easily serialize them back to the browser. Clojure doesn't have a great charting library right now - one could pretty quickly wrap a handful of basic chart types and have a working vega-lite spec generator.
