Having moved to LA this february, the sprawl is really something I had no true appreciation for until I moved here for real, and tried to run errands across town. It's a gigantic, beautiful, complicated place.

I noticed most of the tall buildings are sixties to eighties. Some more info about that here. https://www.pbssocal.org/shows/artbound/a-brief-history-of-l...

Bit misleading since it only shows properties still standing, seemingly. So the older periods look extremely empty.

I did a project recently where I extracted every Los Angeles building permit record for a property and was able to look at the evolution of its infrastructure and tenancy over time by embedding the permit documents into an image-based embedding model. Could be an interesting way to incorporate more granularity of the history of properties over time, although it dramatically increases the scope of data processed.

Nice! Would be better if it shows the difference between the ocean and other land

wild to see that, reminds me vaguely of the amazing ariel photos by kite of San Francisco after the earthquakes in 1906

early 1900s to early 2000s was a wild and crazy ride for humanity

when I was a teenager I used to run early morning before sunrise and I would never see a car, like maybe once per hour

but these days it's like rush hour at 5am which is frustrating and annoying

and then I realized in perspective that within my own lifetime from teen to 60 the world population has more than DOUBLED, so what I am experiencing makes some sense in that regard (plus technology advancement)

Yey yet another vibe coded viz. these are the “hello world” of LLM projects.

nifty. what about this makes it HN worth? What cool problems did you (not the robot) solve? What did you do beyond prompting it, is there anything for others to learn from? Was the data difficult to acquire, clean up, or is this just an obvious viz on a public dataset anyone could get? Did you glean insights from having this viz, does the graphic serve a narrative or distilling information not otherwise apparent, or is it just pretty?

I ask these genuinely. It’s the difference between “oh I figured out how to print ‘hello world’” vs “I built something”
