What is the difference between a treemap and a heat map?
Heat Map: Heat map is a sort of viewing instrument that is very suitable for comparing various categories. With the help of colors and sizes, it allows you to compare one or several sizes and up to two measurements against dimensions. The design is comparable to a text table with color-coded values. A broad range of data can be found rapidly on the thermal map. In a heat map, a color can be determined by one criterion and the size can be allocated by another. The below example shows sales and profit for the distinct categories and subcategories of goods in all areas. Visualization analysis: the profit is shown in color and varies from red to loss to yellow to profit. Total sales are shown by the dimensions. The output of distinct products in distinct areas is therefore very simple to comprehend, at one glance only by looking at the heat map. Tree Maps: Treemaps in Tableau, which appeared in release 8.0, are a fairly fresh function. A "treemap" is a sort of diagram that shows the relations through rectangles in a hierarchy and/or in part. These rectangles are nestled in the event of hierarchy (tree-structured) information. The view room is split into large and ordered rectangles. The measurements are ordered. Nested rectangles mean that hierarchic concentrations in the information are expressed in bigger (above hierarchical) rectangles that contain lower (below hierarchical) rectangles. The rectangles on the treemap range between the top-left corner of the diagram and the lower right-hand corner, with the biggest rectangle located at the top-left corner. To generate such a map, a treemap with 1 or more dimensions and up to 2 measures are used. A below example shows sales and profit for distinct categories and subcategories of goods in all areas. Visualization Analysis: Profit (colour) and product sales (size) are provided at the level of category and sub-category. When the node is larger, sales in that state are higher. Likewise, the greener the node, the more benefit there is.
