(Tableau Visual Analytics)    1-TreeMap: --------------------------------------- 1-Use treemaps to display data in nested rectangles. You use dimensions to define the structure of the treemap, and measures to define the size or color of the individual rectangles. 2-Treemaps are a relatively simple data visualization that can provide insight in a visually attractive format 3-: A slight disadvantage of using treemaps in Tableau is that, as the number of items increases, the amount of space allocated for each item decreases. Hence, the area available to print the labels becomes small. As a result, usually, in a treemap, almost all the squares or nodes will appear blank. This defect can be overcome by providing appropriate tooltips for each node. Like in heat maps, measures can be assigned to give different  colors and sizes to the nodes in the treemap   -------------------------------------------------------------------------------------------------- 2-...
