Datascript has really interested me as of late. I have not done much extensive work with it, but the prospect of its use within a rapid prototyping environment seems promising.

Effectively, it's a Datomic like client side database implemented in ClojureScript with regular JavaScript bindings. The JSFiddle below uses datascript as a local datastore and loads it with data. Then using datalog, it builds up the data series chart configuration required by Highcharts.

The interesting thing to me is having a generalized data store. I'm unconcerned with where i get data and its shape, i simply map it all into datascript and use the query language to pull out exactly what I need.

For example, converting bytes to MB and obtaining the min/max/avg values is very easy. 

[ :find (avg ?dataSize) (max ?dataSize) (min ?dataSize)
  :where
  [ ?e "dataSize" ?ds ]
  [(/ ?ds 1048576) ?dataSize]]
