Any attempt to re-imagine programming is refreshing, but it's unclear to me if this is more than a domain specific language (DSL). Is it possible to implement, for example, the bar graph from lower primitives?
You can build charts like this in svg or html right now. Basically, in Eve we are just generating the records necessary to render these views. We have a separate process that's tied to the browser that takes these records and turns them into something the browser can understand. So Eve isn't tied to html; if you write your own translation layer (and we will have many more by default in the future) then Eve can generate whatever you want.
