[OC] I built a pet project to visualize Olympic race data. Here is the Geographic Bubble Map of the Men’s and Women’s Skiathlon results.

Hi everyone!

I'm building a small website that visualizes race results for endurance winter sports – XC Skiing, Biathlon, and Skimo. Pre-race predictions, post-race analytics, various chart types.

Here are two examples from the 2026 Olympics in Tesero – Geographic Bubble Maps for the Men's 20km and Women's 15km Skiathlon.

Each bubble represents a participating country. Bubble size reflects athlete count, while color intensity indicates average finishing position: vivid for top performers, washed out for lower ranks.

Tools: React, Recharts, custom SVG with force-directed simulation (TypeScript) for the bubble map layout

Data source: FIS-SKI official results

Visualization: endurance-analytics.com

Disclosure: I'm a backend developer. To build this visualization, I teamed up with my wife for design and used AI agents to handle the frontend implementation.
