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

Background

Fan Chart

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

And a number of graphical reports for printout:

  • Classic family tree(s)
    • Ancestor Tree
    • Descendant Tree
    • Family Descendant Tree
  • Fan chart
  • Timeline pedigree

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.

Feature request "4649: GeneaQuilts visualization integration" asks for this functionality.

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.


TimeNets

TimeNet

This is a type of timeline tree.

Wilfried Trabold pointed this out on the gramps-users mailing list in December 2010. Gerald 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.
