Bar missing min, max and compute

[mfirry]

The javascript version looks like

export default function({data, accessor = id, width, height, min, max, gutter = 10, compute}) { /*... */}

Are we missing anything here?

You are right for min and max. compute is only there for those ecosystems where the template rendering system does not allow computed properties (i.e., mustache) and is a pain to write a type for, so it will not be supported in the scala.js version
