Leaflet Version 7

The Leaflet module features:

• Field formatter that can show a map for fields that contain geospatial data.
• Views integration that plots data on a map (using the sub module Leaflet Views).
• Lightweight and easy to use API for defining maps and displaying data on a map.

Some modules that build on Leaflet, adding various features:

• Leaflet More Maps: adds over 20 map styles, selected at the flick of a drop-down
• Leaflet Label: alternative tool tip hovers for polygons and line strings
• Leaflet Hash: bookmarking for maps, appends a hash of current map center and zoom to the URL, so you save and restore the "view port"
• Leaflet MarkerCluster: makes large marker populations easier to navigate through animated clustering and drill-down capability
• IP Geolocation Views & Maps: adds a swag of cool features such as centering options, markers colour-coded by any field in your View, cross-highlighting between content and map, geocoding and reverse geocoding options.
• Many more...

D7 version originally developed by ThinkShout and @pvhee (from Marzee Labs) with lots of help from the community.
