  2. Graphviz - Wikipedia

    en.wikipedia.org/wiki/Graphviz

    ArgoUML's alternative UML diagram rendering called argouml-graphviz. [5] AsciiDoc can embed Graphviz syntax as a diagram. Bison is able to output the grammar as dot for visualization of the language. [6] Confluence has a Graphviz plugin to render diagrams from text descriptions. ConnectedText has a Graphviz plugin.

  3. Shortest-path tree - Wikipedia

    en.wikipedia.org/wiki/Shortest-path_tree

    Example of one of two shortest-path trees where the root vertex is the red square vertex. The edges in the tree are indicated with green lines while the two dashed lines are edges in the full graph but not in the tree. The numbers beside the vertices indicate the distance from the root vertex.

  4. Quadtree - Wikipedia

    en.wikipedia.org/wiki/Quadtree

    A node of a point quadtree is similar to a node of a binary tree, with the major difference being that it has four pointers (one for each quadrant) instead of two ("left" and "right") as in an ordinary binary tree. Also a key is usually decomposed into two parts, referring to x and y coordinates.

  5. Treemapping - Wikipedia

    en.wikipedia.org/wiki/Treemapping

    The Product Exports Treemaps are one of the most recent applications of these kind of visualizations, developed by the Harvard-MIT Observatory of Economic Complexity. In information visualization and computing , treemapping is a method for displaying hierarchical data using nested figures, usually rectangles.

  6. Tree (graph theory) - Wikipedia

    en.wikipedia.org/wiki/Tree_(graph_theory)

    In graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph. [1] A forest is an undirected graph in which any two vertices are connected by at most one path, or equivalently an acyclic undirected graph, or equivalently a disjoint union of trees. [2]

  7. Tree diagram - Wikipedia

    en.wikipedia.org/wiki/Tree_diagram

    Attack tree, conceptual diagrams showing how a target might be attacked; Fault tree diagram, diagram used in deductive failure analysis in various industries; Program structure tree, hierarchical diagram that displays the organization of a computer program; Treemapping, a method for displaying hierarchical data using nested figures, usually ...

  8. Tree structure - Wikipedia

    en.wikipedia.org/wiki/Tree_structure

    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.

  9. Dendrogram - Wikipedia

    en.wikipedia.org/wiki/Dendrogram

    A dendrogram of the Tree of Life. This phylogenetic tree is adapted from Woese et al. rRNA analysis. [3] The vertical line at bottom represents the last universal common ancestor (LUCA). Heatmap of RNA-Seq data showing two dendrograms in the left and top margins. A dendrogram is a diagram representing a tree. This diagrammatic representation is ...
