In our example, we show the countries divided by the geographical parameter, and the values they show are their area. This way of arranging the data is expected by a TreeMap as a default. Let's now take a look at both ways of arranging the data.

"parent": this parameter in necessary for all elements (nodes) of the tree, except for the root if you have several points with no parent, the first one will be considered as a root, others will be ignored.The long-standing dilemma of reloading a webpage for every new command has been solved by the introduction of this miracle of technology called ‘JavaScript’. "size": numerical parameter which defines the point's size unless being defined, value paramater will be considered a size Programming languages such as JavaScript enable dynamic user interaction with websites and mobile applications.If this parameter is not set, this point will be valued as missing and won't be displayed "value": numerical value which usually defines the point's color (colors are distributed by the color scale by default unless some points have specially defined colors).This parameter is necessary for all elements, or nodes "id": a unique parameter that identifies the point.Regardless which way we decide to use, there are some parameters we have to define to all points. As TreeMap is intended to work with hierarchies, you can set the data in one of two available formats: as an hierarchical tree and as an hierarchical table. Working with data in An圜hart TreeMaps is quite simple. This diagram is an upgraded version of the Marimekko chart. If one of those elements appears to be a parent element too, it will be shown in the header and its children will be demonstrated within it. Child elements look like rectangles of relative dimensions which depend on the values these elements represent. TreeMap with Flat Collection: If HeaderTemplate is specified for TreeMapLevel, then the header can be bound by referring Header object to the data template. For customizing default Header appearance, you can specify the HeaderTemplate. The top rectangle is a parent element, unless you drilled down into a structure. To show headers in TreeMap, you can set the HeaderHeight property of TreeMapLevel.

Treemap chart is a tree designed as a rectangle divided into a set of rectangular elements. TreeMap is intended to demonstrate hierarchically ordered data structures, where all elements have a parent element, except for the root (the highest/eldest element in the hierarchy). It provides web developers with a fantastic opportunity to design various charts that will aid in data analysis and data-driven decision-making. An圜hart is a feature-rich, lightweight, and robust JS chart library that renders in SVG/VML.
