The purpose of this GEP is to discuss new visualization techniques for possible inclusion in Gramps.
Contents
Background
At present Gramps offers two graphical visualizations of genealogical data as views:
- Pedigree View (Classic family tree)
- Fan chart (since Gramps 4)
Some Addons:
- TimelinePedigreeView
- GraphViz and Goocanvas: Graph View
A number of graphical and GraphViz based reports for printout:
- Classic family tree(s)
- Ancestor Tree
- Descendant Tree
- Family Descendant Tree
- GraphViz based
- Addons
- InformationGraph (Gramps 3.2.x, GraphViz based)
- DenominoViso
- Family Tree
- "Non-standards" Addons
As well as a graphical default gramplets:
- Fan Chart Gramplet
- "Textual bloc/area/tree informations" gramplets
In the last few years papers have been published describing new visualization techniques.
Quilts
Family trees are presented in the form of a grid.
A video, demonstration software, and a paper describing the technique can be found on the Aviz website.
Status: A Gramps implementation is currently being written (Nick Hall). See Feature request "4649: GeneaQuilts visualization integration"
TimeNets
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
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
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.
The Gene-Tree
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.
