ADF Thematic Map in ADF 12c (12.1.3)

ADF Thematic Map component from DVT library was updated in ADF 12c with marker zoom option and area layer styling (ADF 12c (12.1.3) new features). I have decided to check how it works and implemented quick sample application -

I was using world GDP data (SQL script is available together with sample application) and displayed it using ADF Thematic Map. World country borders are hidden on purpose, borders are visible by default:

While zooming, marker points are growing - very useful feature:

Data for thematic map is fetched using SQL based VO. I'm calculating total GDP and taking percentage from total for the country, this allows to scale marker points better:

ADF Thematic Map is configured to support zooming for markers:

Countries area layer is set to be hidden, although data is still gets attached to the countries:

Marker is configured with dynamic scaling, this is how each country gets appropriate marker size, based on its GDP value:

Marker colour property is set to be dynamically calculated in marker Attribute Groups section:
