A simple family tree visualizer

How to use

Create family.txt for your family
Put any photos into the photos directory
Change the first few lines of family.js

Format of your family.txt file

This file will contain

entries for couples, including their list of offspring
optionally, entries for individuals, including their lifespan and photo

Entries for couples are formatted like this:

Name One + Name Two
c: Child A, Child B, Child C
n: Notes line(s), optional

If there are no children or no notes, leave those lines out.

Entries for individuals can contain a lifespan, photo, and notes.

Name Of Person
l: 1912-Dec 2100
p: photo_filename.jpg
n: Notes line(s), optional

All lines are optional, and if you have no lines, you need not fill out an entry for someone. Lifespans can be of the forms start-end, start- or -end.

Here's a simple example file with 2 entries (one couple, one person) and 5 people total:

Homer Simpson + Marge Bouvier
c: Lisa Simpson, Bart Simpson, Maggie Simpson
n: Married while pregnant with Lisa
Homer Simpson
l: 1951-
p: homer.jpg
n: Nuclear Safety Inspector in Sector 7G

UI

The bar at top allows switching the level of detail shown
Click on a person to make them the root of the tree
Hover over a person to show all notes for them and their partners

Data Tricks

You can leave someone's name as ? if you don't know it. (Should be a parent or child's name in a couple's entry.)
Put comments in your family.txt by starting them with #
Multiple people with the same name can be disambiguated by putting a # after their name, followed by a distinct identifier (which will not be rendered). Example:

King George#Older + Mary of Teck
c: King George#Younger

http/s URLs in n: notes lines automatically are turned into links. They can't contain spaces.

Data Limitations

This program can only handle topological trees, not marrying extended family or two marriages between families
Names shouldn't contain commas
If person X has two spouses, you need to list them as the first person in one couple and the second person in the other. E.g. Partner1 + X and X + Partner2. This is because the rendering engine uses the order in each couple as literal positional instructions
This program can't handle someone who has had more than two spouses/partners

Disclaimer

Use your judgment when posting sensitive family information on the internet, e.g. you may consider using .htaccess or some other appropriate security.
