This is a simple example of a map of the USA. We added a few markers that could indicate office locations or something else. You can then specify an action for the markers, in this case we created a custom action to display HTML information below the map. The plugin already comes with built-in actions like opening a new link or display an alert message. You can specify colors of the markers and the color for the US map.
For instructions on how to build this custom action, check out this other example of a world map with office locations.
With this wordpress plugin you can create as many maps as you want!
