Structure
This article describes the inner structure and organization of the elements which build RadHeatMap.
RadHeatMapElement is the main element that contains one StackLayoutElement that holds the HeatMapTitleElement.
RadHeatMap doesn't use visual elements but renders its cells directly according to the calculated rectangles. Every colored cell is represented by a HeatMapItem with a value. According to the applied colorizer, the cell rectangle is filled with the appropriate color.
