Zooming and Centering
Documentation
This demo shows the VectorMap zooming and centering capabilities. The map contains several cities represented by dot markers. To identify a city, pause on its marker, and the name of the city will appear in a tooltip. Moreover, if you click the marker, the map will be zoomed and centered on it. In code it is performed by calling the center(centerCoordinates) and zoomFactor(zoomFactor) methods. A click on the «Reset» button restores default center coordinates and zoom factor.
