genealogic-d3

KISS genealogy tree visualization depending on d3.js only.

Demo

https://chezsoi.org/lucas/genealogic-d3/skywalker.html

Installation

This tool can only display tree-like genealogies, e.g. all nodes are descendants of one given ancestor, like in a pedigree tree. It won't be able to render generic genealogy graphs with non-unique root ancestor.

A basic setup requires only to put 3 files in a directory, and you'll be able to view the result locally with a browser:

• genealogic-d3.js
• an HTML file (cf. index.html template)
• a JSON 'genealogy' file, describing a descendants tree
• optionally, a subdirectory containing miniatures .jpg images, named after the genealogy nodes .name attributes.

JSON genealogy structure :

{
  "name": "Node name",
  "caption": "Optional caption",
  "miniature_img_url": "Optional image url",
  "partner": {
    // Optional node with all standard attributes available, except .children
  },
  "children": [ // Optional
    {
      // Recurse
    }
  ]
}

You can check the skywalker_genealogy.json for a complete example.

index.html template

For the needs of the demo, skywalker.html is a bit verbose. There is a basic HTML file skeleton to use genealogic.d3 :

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.4.13/d3.js"></script>
<script type="text/javascript" src="genealogic-d3.js"></script>
<svg width="1000" height="1000" id="genealogic-tree"/>
<svg id="genealogic-miniature"/>
<script type="text/javascript">
genealogic.generate({
    json_input_genealogy: 'my-family-genealogy.json',
    path_to_miniature_imgs: 'miniatures_dir/'
    use_fixed_miniature: false, // Defaults to true
});

Parameters

• svg_tree_selector : CSS selector to the main HTML element where the tree will be inserted.
• json_input_genealogy : URI to the JSON genealogy file, or a javascript genealogy dictionary
• path_to_miniature_imgs : miniatures images directory URI. If this evaluate to false, only miniatures specified through the optional .miniature_img_url attribute will be used.
• miniature_img_ext : the miniatures image files extension
• use_fixed_miniature : whether to use a unique floating circle to viusalize miniatures, or else embed them inside each node circle
• miniature_svg_selector : CSS selector to the HTML element that will be used as the miniature "window".
• miniature_photo_size : in pixels
• packing_generation_factor : control the differences in sizes of the node circles: it must always be higher than the tree max depth, with high values meaning that all circles will be the same size
• d3_color_scale : cf. https://github.com/mbostock/d3/wiki/Ordinal-Scales#categorical-colors
• wrapped_text_line_height_ems : spacing in ems between names / captions multiple lines when text needs to be wrapped
• post_rendering_callback : if defined, this function will be executed once d3.js rendering over

The list of all those parameters default values can be found in the source code here: https://github.com/Lucas-C/genealogic-d3/blob/master/genealogic-d3.js#L3

Notes

This visualization tool can be combined with an 'upload-and-crop-your-own-picture' plugin, to let members of the family upload their photos themselves. E.g. :

• https://github.com/acornejo/jquery-cropbox
• https://github.com/TuyoshiVinicius/jQuery-Picture-Cut
• https://github.com/andyvr/picEdit

Also, this is a useful command to list missing miniatures:

diff <(jq -r '..|objects|.name' genealogy.json | sort) <(ls miniatures | sed 's/\..*//' | sort)
