I went about looking for at least a draft level spec. All I could find was: <a href="https:&#x2F;&#x2F;uwdata.github.io&#x2F;vega-lite&#x2F;spec.json" rel="nofollow">https:&#x2F;&#x2F;uwdata.github.io&#x2F;vega-lite&#x2F;spec.json</a><p>I love the concept, but since this is presented as a &quot;grammar&quot;, it would make sense to provide a specification of it, in addition to the examples.<p>Great work!
