We're in the middle of adopting in Western Australia, and like everyone going through this process, we've been buried in paperwork. One of the requirements from the Department of Communities is a genogram — a clinical family diagram that maps your family structure using standardised symbols for relationships, marriages, separations, and parent-child connections including adoption and fostering.
I'm a web designer and tinkerer, so when I couldn't find a free tool that produced the right clinical format, I built one. It started as something just for us, but I figured if we needed it, others probably do too.

It's completely free, no ads, no account, and open source. Everything runs in your browser — your family data never leaves your device. You can export a clean SVG to attach to your documentation, or import a GEDCOM file if you've already got a tree on Ancestry or MyHeritage.
Adoption paperwork is already exhausting. I hope this makes one small part of it a little easier for someone.
Happy to answer any questions, and if you spot something that needs fixing or a feature that would help, let me know.
