Percentile

interactive polygons from a reference map.

tooltips can be displayed when mouse is over segments, on click actions can be set with javascript instructions.

Usage
geom_map_interactive(mapping = NULL, data = NULL, map, stat = "identity", na.rm = FALSE, show.legend = NA, inherit.aes = TRUE, ...)
Arguments
mapping
The aesthetic mapping, see geom_point.
data
A data frame, see geom_point.
map
Data frame that contains the map coordinates. See geom_map.
stat
The statistical transformation to use on the data for this layer, as a string, see geom_point.
na.rm
See geom_point.
show.legend

# create tooltips and onclick events
