I'm delighted to see this on the front-page of HN. I hope it's standing up to the HN hug!
It's been a real pleasure to have a hand in something that continues to help people after all this time. CCBV was a group project during a hackday in Feb 2012. Having this here makes me realise that we're only a couple of days past the 10th "birthday" of the website's first commit :)
Edit: As others have pointed out, there's a typo in the title. It should be "Django", rather than "Dango".
I don't know if it's within the rules, but I suggest that the link should be changed too, as the main page (https://ccbv.co.uk/) has more information -- the current article link is to a relatively boring index for the classes in Django 4.0.
Check out django-schema-graph. I hope you like it!
