This is an example of a US map created with the interactive maps plugin.
United States Map
You can choose any color for the state, or even leave states out, without any interaction.
In this case we used a sequential color scheme to exemplify what you can do. For reference I used colorbrewer.
You can easily set the states clickable, redirect it to a URL or display more info below or above the map.
Together with the map of the US, you’ll have access to all other kinds of maps, including a map of the work, divided by countries, continentes, or subcontinentes, or display in more detail other countries.
