A Cartogram plots two measures on a map that uses circles or squares, instead of the traditional regional borders. On top of allowing for comparing two magnitudes, this map type is also useful for making significant regions more visible. Available are region, country and states maps.The column containing area names should be selected in the Label Field. The areas will be shaped based on the magnitude selected for the Measure Field. Circles based on the magnitude selected for the Measure Field will appear on designated locations. Color Field adds the second dimension, showing this second measure on the nodes and adding a color legend.Please note that the Measure and Color need to contain numeric fields and remember to select an Expression for each of these fields by choosing from the drop down.
