The purpose of this GEPS is to discuss new visualization techniques for possible inclusion in Gramps.

Background

Descendant Fan Chart View - full circle

At present Gramps offers two graphical visualizations of genealogical data as views:

Some Addons:

A number of graphical and GraphViz based reports for printout:

As well as a graphical default gramplets:


In the last few years papers have been published describing new visualization techniques.


Quilts

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.

Status: See Feature request "4649: GeneaQuilts visualization integration"

Quilt view (Gramps 4.2.1 Windows 7)


TimeNets

TimeNet

This is a type of timeline tree.

TimeNets, enable analysis of families over time, by prioritize temporal relationships, in addition to the family structure. Individuals are represented using timelines that converge and diverge to indicate marriage and divorce; directional edges connect parents and children.

Note: Wilfried Trabold pointed this out on the gramps-users mailing list in December 2010. Gerald Britton[1] was in a side-discussion with the authors to explore the possibility of working together to include this in Gramps.

Status: Not known.

Dual Trees

Dual Trees

This is a method of combining graphs in a single display.

  • Bi-directional top-down node-link diagrams
  • Used for navigating genealogical graphs (family “trees”)

Status: Unexplored.


The H-Tree

The H-tree

A structured, space-efficient technique for pedigree visualization (to display ancestral trees).

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 6389 for a working trial for Gramps 3.4.2 windows portable and Gramps 4.1.1(with minor file changes)

H-tree trial(5 generation(31 people shown)(Gramps 4.1.0 Windows 7)


The Gene-Tree

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.
