This shows an interactive map of South Korea. The map is subdivided into the provinces. Each one of them has its own color and a tooltip that becomes visible when the mouse is above the corresponding province. Whenever one of the colored provinces is clicked, it will open a link in a new window. The URL can be set individually for each region. This resulting map is shown here:

It is also possible to choose other click actions. For example, the links could also be opened in the same window. Or further information could be displayed below the map when a province is clicked.
