Series-Based Approach

• Multi-type series
  • Everything on the maps is organized in "series": areas/countries (polygons), markers (images), lines.
  • Makes it super easy to apply appearance settings or attach behavior to a bunch of elements at once.
  • Series-based approach allows easy structuring of elements, toggling, and other control.
  • It also allows specifying what exactly to include or exclude from GeoJSON. Do you want just a map of Europe? Simply specify country codes that you want to be included. A world map without Antarctica? Specify to exclude it from the map.
• Combining multiple maps
  • Multi-series support also means you can combine multiple maps on the same chart.
  • Want to add U.S. states on the World map? No problem at all.
• Line series
  • Map Chart's line series allow adding basic or complex routing maps, connecting existing markers or arbitrary points.
  • As with anything else on amCharts, lines are fully configurable.
  • Make them straight, bent, or follow natural Earth ground curvature.
  • Add and position images on them, as well as make them follow relative rotation.

Useful Functionality

• Projections
  • amCharts comes with support for a lot of map projections.
  • Projections allow displaying the same map in different ways.
  • The following projections are already supported with more planned: Eckert6, Equirectangular , Mercator, Miller, and Orthographic.
• Coordinate shifting
  • The map is not constrained to be centered on a single point. You can set your own center coordinates, meaning you can create a map centered any way you like.
  • Easily create a Pacific-centered world map with just a single configuration option.
  • Or how about a rotating globe by combining coordinate shift with an Orthographic projection?
• Heat maps
  • amCharts brings a very powerful "heat rules" functionality, which you can use with maps as well.
  • Basically, you can bind most of the element's properties to a numeric value. E.g. color fill of the countries, based on their fields in data, allowing you to create heat maps.
  • And, of course, you have a "heat legend" control as well.

Built-In Controls

• Zoom control
  • Just a single line of code adds neat control your users can use to zoom in and out the map.
  • Another line enables the slider.
  • All elements can be controlled using mouse, touch, and are accessible controls, enabling keyboard control.
• Mini map
  • Another easily-enabled control shows "bird's eye" view on the map.
  • It will mark the position of the current viewport on a tiny version of the whole map.
  • And, of course, it supports multiple map series, so it is as functional as the map itself – add mini versions of polygon, image, or line series there.
• Heat legend
  • A heat legend allows automatically showing the "heat scale" of the map areas.
  • It takes the whole range of values and heat colors, then builds a value/color scale.
  • And, best of all, it can display an indicator of where a particular area is within the scale.
