At present Gramps offers two graphical visualizations of genealogical data as views:
* [[Gramps_4.0_Wiki_Manual_1_Wiki_Manual_-_Categories#Pedigree_View|Pedigree View]] (Classic family tree)* [[Gramps_4.0_Wiki_Manual_1_Wiki_Manual_-_Categories#Fan_Chart_View|Fan chart]] (since Gramps 4)
Some Addons:
* GraphViz and Goocanvas: [[Graph_View|Graph View]]
A number of [[Gramps_4.0_Wiki_Manual_1_Wiki_Manual_-_Reports#Graphical_Reports|graphical]] and [[Gramps_4.0_Wiki_Manual_1_Wiki_Manual_-_Reports#Graphs|GraphViz based]] reports for printout:

== Quilts ==
[[Image:Quilt.gif|right|thumb|350px400px|Quilt]]
Family trees are presented in the form of a grid.
Quilts allow the visualization of large genealogies up to several thousand individuals, by using a diagonally-filled matrix, where rows are individuals and columns are nuclear families.
A video, demonstration software, and a paper describing the technique can be found on the Aviz website.
== TimeNets ==
[[Image:TimeNet.gif|right|thumb|350px400px|TimeNet]]
This is a type of [http://en.wikipedia.org/wiki/Timeline timeline tree].
== Dual Trees ==
[[Image:DualTrees.gif|right|thumb|350px400px|Dual Trees]]
This is a method of combining graphs in a single display.
The H-tree based layout can be used to display ancestral trees. This layout increases the number of displayable generations, via a symmetrically arranged structure, provides the the user with an overview that allows them to understand and navigate through the data.
Status: See {{bug|6389}} for a working trial for Gramps 3.4.2 windows portableand [[Addon:HtreePedigreeView|Gramps 4.1.1]](with minor file changes)

== The Gene-Tree ==
[[Image:cranefoot.png|thumb|350px400px|The gene-tree (Cranefoot)]]
A structured, space-efficient technique for pedigree visualization (to display ancestral trees), using colors and symbols. This type of tree is often used for medical usage.
Status: Unexplored.
