MapChart

Description

The MapChart component is used to show and set up a map based on an SVG topobase.

The following objects can be displayed on a map:

• Arrows to show streams between regions or countries.

• Milestones, for example, to show cities and towns.

• Bar and pie charts for visual data view.

• Map legend.

• Territory info.

• Tooltips.

• Labels.

• Timeline.

Map settings and various effects can be defined in the XML file or from API.

Comments

The component is implemented by MapChart class.
