I visualized the entire history of Citi Bike in the browser
Each moving arrow represents one real bike ride out of 291 million, and if you've ever taken a Citi Bike before, you are included in this massive visualization! You can search for your ride using Cmd + K and your Citi Bike receipt, which should give you the time of your ride and start/end station. Everything is open source: https://github.com/freemanjiang/bikemap Some technical details: - No backend! Processed data is stored in parquet files on a Cloudflare CDN, and queried directly by DuckDB WASM - deck.gl w/ Mapbox for GPU-accelerated rendering of thousands of…

In plain words
This visualization displays all 291 million Citi Bike rides as animated arrows moving across a map in the browser. Users can search for their own rides using their Citi Bike receipt to locate their trip among the dataset. Built with no backend infrastructure, it uses DuckDB WASM to query parquet files stored on Cloudflare's CDN, with GPU-accelerated rendering through deck.gl and Mapbox to animate thousands of concurrent bike routes. The project is open source and designed for anyone interested in exploring New York City's bike-sharing data and patterns.

ADS-B visualizer2024 · adsb.exposed · ▲339I've created a web app for querying and visualization of ADS-B datasets: https://adsb.exposed/ Source code: https://github.com/ClickHouse/adsb.exposed/ The results significantly exceeded my expectations because the pictures are insanely beautiful, and the data is a treasure trove. It proves many statements that were not certain: - it is feasible to generate tiles by aggregation on a pixel level (instead of hexagons or rectangular grid); - it does not require JPG/PNG tiles - we can transfer raw bitmap data with zstd compression; - it is possible to…
I built a transit travel time map2023 · map.henryn.xyz · ▲255This was something I built while trying to look for housing in Toronto that was decently transit-accessible to my office while still cheap. The backend is written in Rust. It parses public GTFS data from transit agencies and performs a simple heuristics-based BFS on the bus lines to calculate how long to reach all points in a city. The frontend uses React and Mapbox GL to render each individual road segment based on how long it takes to reach. This project was a great excuse to learn Rust, deployments, and mapping. The source code is here if you are interested:…
- TBTracking bike-share movement over New Year in Zurich2024 · publibikes.tibaldo.ch · ▲23
In Switzerland PubliBike is a popular bike-sharing company. Thanks to its openly accessible API one can extrapolate the movements of these bikes around the cities. As a Christmas project I decided to collect this publicly available data and visualize the movement of bikes in the city of Zurich. Purple tracks are classic bikes, while blue tracks are electric bikes. I am not well versed with front-end development so I hope you will excuse the mediocre interface. Happy to take any questions, comments, feedback and thoughts. A good new year to all of you! GitHub repo:…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
