24 alternatives to Interactive map of the convenience store "turf war" in Japan
Technologies used: Leaflet (frontend) Turf (Geojson generation and Voronoi generation) I noticed that my neighborhood is all Lawsons, so I got the location of all Conbinis and ran some basic analysis to see if these pockets of brand territory are common. I haven't worked much with web frontends before, so feedback is welcomed. I also have some ideas to maybe expand upon, like making the territory calculations based on streets and other geographical features rather than just beeline distance. The site isn't tested too much on mobile yet, but should be ok. Currently the frontend code and…
This interactive map visualizes territorial patterns of Japan's convenience store chains by mapping all store locations and calculating their market coverage areas using Voronoi diagrams. Built with Leaflet and… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Interactive map of the convenience store "turf war" in Japan launched in 2024; newer entries below may have overtaken it.

Hi HN, I made a web game to practice country locations a while ago and HN liked it, so I thought I'd post my updated version as well. As for how the game works and feels, I'd really recommend you checking it out for yourself, it's free, no signup, no ads. The tech stack is Vue + ts + Tailwind/Daisy for the looks. The learning algorithm is a slight modification of the ts version of FSRS. If you have anything to add, it's open source as well (https://github.com/koljapluemer/learn-worldmap), although not well documented yet. In the end it's just a little sideproject,…

Hey Everybody! Hope you had a merry christmas Today I had a bit of fun with Claude. Started by scraping YC's startups list, then ran them through OpenAI's embedding service, then UMAP'd the embedding to reduce the dimension to just two coordinates and then just forced Claude to write React that would compile to visualize that. I had fun and I think it's interesting, so take a look! Also note that you won't be able to zoom on mobile (found about this Plotly limitation way too late). If there's interest I can fix this issue by changing plotting libs tomorrow :) Merry christmas

For the past few months, I've been working on a website that answers two different questions: - Where in my city have the best travel times to all the things and people I care about? - Given a listing, how far is it from all the things and people I care about? Personally this was fueled by my own frustrations when I was apartment hunting in NYC. I was frustrating to have to juggle so many Google Maps tabs when I was evaluating a listing, and it was also annoying to not have full confidence that I was even searching in the right places. I wanted to be close to work, a Trader Joe's, and a…

I've posted this game here before, hopefully a repost is fine as the game has changed quite a bit (improved AI, improved mapeditor, much quicker gameplay, etc). Game is based on JavaScript/Canvas and WebSockets. On the browser side the map is pre-rendered (as a background image), just the mobile units/buildings and animations are dynamically rendered. The lobby server is made in node.js, but the game server is C++ for performance reasons (mainly the pathfinding). I found the C++ WebSocket libraries out there to be too difficult to use so I made my own based on the rfc. Overall I…

Just a fun hack I did while bored over the weekend. My wife was busy shopping, it got me thinking that can VLMs solve the indoor location problem in a mall? Can I just show a VLM a map and an image and have it doa good enough job locating me? I hacked this P.O.C and it seems to work.

Hi HN, I built a little tool to help me get better at remembering country locations on the map: https://learn-worldmap.netlify.app/ It's made from plain HTML/CSS/JS, and not intended to make any money or anything. Just thought that maybe someone else may enjoy it. Also of course happy about any feedback! Cheerz.

Try it: We mapped 2,970 Y Combinator companies in 3D by product similarity - 57% of YC's entire portfolio since 2005. Jump right in and explore: pan/zoom around, click for detailed profiles, explore clusters. No signup required, works best on desktop. Why Sometimes it's hard to grasp the bigger picture and see the forest for the trees. This map gives an overall representation of the whole space - companies, clusters, and outliers (companies that don't have obvious similar counterparts). For example, there are three companies supporting innovation labs. Also it's fun to see how LegalTech…

Last weekend, I tried creating an original visualization of something on many minds in my home country the Netherlands: land use. Much of our discussion revolves around land use—housing crisis, sustainable farming, solar energy—it's all about the land. To illustrate this, I created a map where each hexagon represents 0.06% (26,647 hectares) of land in the Netherlands. The color indicates the type of land use.

My name is Adrian. I'm a Software Engineer and I spent 6 years developing a perimeter-based geofence-based social media app. What it does: - Allows you to load a custom perimeter anywhere on the geographic map (180° E and W longitude and 90° N and S latitude), to cover area any area of interest - Chat rooms get loaded within the perimeter - You can chat with people within the perimeter I developed a mobile app that uses an advanced geofence-based networking system from 2013 to 2019. My goal was to connect users within polygon geofences anywhere in the world. The app is capable of loading…

Hello HN, Long-time lurker, first-time poster here. I've created a service that creates a "flow map" of your mobile app. Check it out at: https://prodscape.net. The goal is to reduce last-minute regressions, promote holistic discussion, and help develop more ownership within an organization. This is something that I would have liked to have had when I was working at a big company. Some caveats: 1.) Only iOS is currently supported but Android-support will be coming soon. 2.) You need a developer-signed IPA file (see the guide on creating an IPA file here:…

I couldn't find a simple way to explore the Brazilian startup ecosystem geographically, as I can in other places like the Bay Area or London, so I built one. The map currently includes hundreds of startups from Sao Paulo and their job opportunities. The most interesting thing I've learned so far is how clustered startup activity is in a handful of areas. I'd love to hear your thoughts. The EN version: https://www.startupsbr.com/sao-paulo
