 Alternatively, Carto can be used from JavaScript.
 The `Renderer` interface is the main API for developers, and it takes an MML file as a string as input.

 If you want to use CartoCSS within the browser you should not use MML loading via `carto.MML.load`.
 Instead you should supply the JSON of the MML including the Stylesheet strings directly to `carto.Renderer.render`.
