Making maps with ggvis with some examples showing:

- basic map creation

- basic maps with points/labels

- dynamic choropleths (with various scales)

- applying projections and custom color fills

- apply projections and projecting coordinates for plotting

The `R` file lets you play interactively with each example. The `Rmd` file shows what the plots look like in static format. The Shiny code (`ui.R`, `server.R`) provides an interactive version in a Shiny app context.

The `Rmd` has also been published on [RPubs](http://rpubs.com/hrbrmstr/ggvis-maps) and there's a [blog post](http://rud.is/b/2014/12/29/making-static-interactive-maps-with-ggvis-using-ggvis-maps-wshiny/) with slightly more expository than the code.

One of the caveats with `ggvis` is that you need an online context for interactively (making things like interactive choropleths useless without such a context). You'd need to account for this in the `Rmd` by setting up a faux-facet series for the maps, either with a `` or `
` grid.
