In information visualization and computing, treemapping is a method for displaying hierarchical data using nested figures, usually rectangles. Treemaps display hierarchical ( tree-structured) data as a set of nested rectangles. Each branch of the tree is given a rectangle, which is then tiled with smaller rectangles representing sub-branches.
A tree structure, tree diagram, or tree model is a way of representing the hierarchical nature of a structure in a graphical form. It is named a "tree structure" because the classic representation resembles a tree, although the chart is generally upside down compared to a biological tree, with the "stem" at the top and the "leaves" at the bottom.
Graph database. A graph database ( GDB) is a database that uses graph structures for semantic queries with nodes, edges, and properties to represent and store data. [1] A key concept of the system is the graph (or edge or relationship). The graph relates the data items in the store to a collection of nodes and edges, the edges representing the ...
The example also shows how the chart's overall style can be overridden by more specific styles set by {}. In this case, the color of the first row of cells is set to yellow using the features of the {{ Tree chart }} template; see that template's documentation for details on how to specify the CSS of rows and individual cells of a chart.
Usage. This template produces one row in a "family tree"-like chart consisting of boxes and connecting lines based loosely on an ASCII art -like syntax. It is meant to be used in conjunction with { { Tree chart/start }} and { { Tree chart/end }}. The chart is displayed as HTML tables using CSS attributes, and may contain arbitrary wiki markup ...
Template:Tree list/styles.css ( sandbox) This family of templates can be used to create a properly structured and accessible tree. This can be used to display family trees, succession to thrones, etc. They comprise: { { Tree list }} { { Tree list/end }} { { Tree list/branching }}
Usage. This module uses the mw.html library to create rows of table cells whose borders draw lines to show relationships between elements. When an unnamed parameter matches a key in Module:Tree chart/data, the module will create a block with stylings as defined in the table. Each key in the table has a subtable with 0, 1, or 2 keys of its own ...
