Nevron Diagram makes it easy to import geographical data from Esri shapefiles. You can import the shapes in separate layers and control the way they are rendered applying various styles to them. Also additional information is provided for each shape (such as Country Name, Area, Population, Currency, etc.)

This example shows a world population map by countries (darker countries has larger population). A fill rule is used to automatically color the countries on the map based on their population attribute.
