Creating an Interactive Data Visualization of Japan’s Transportation and Convenience Network
In today’s digital age, visualizing complex geographical data in an engaging and accessible manner can greatly enhance understanding and analysis. Recently, I embarked on a project to develop an interactive digital map of Japan that showcases over 8,500 train stations and 55,000 convenience stores seamlessly integrated into a dynamic pixel-based interface.
Introducing Hikarie: An Innovative Geographic Data Visualization
Hikarie is an interactive platform that transforms vast datasets into an intuitive visual experience. Utilizing thousands of small, individually rendered pixels, the map provides users with a detailed and immersive view of Japan’s extensive transportation and retail infrastructure.

Technical Approach and Challenges
Developing this project involved addressing some notable technical challenges, primarily ensuring smooth rendering and interactivity with such a high volume of data points. The core components of the tech stack included:
- Framework: Next.js to build a scalable and fast server-side rendered React application
- Rendering Engine: Pixi.js, chosen for its efficient handling of thousands of sprites and real-time interactions
- Map Logic and Data Handling: D3.js and AmCharts facilitated the geographic computations and data visualization aspects
- Backend Storage: MongoDB stored and managed the extensive datasets
The integration of D3.js with Pixi.js was particularly rewarding, allowing for precise geographic calculations coupled with high-performance rendering.
