Building a Life Expectancy Visualizer with GPT-4o in Minutes

Summary

The author reflects on their birthday and time passing, then describes building a life expectancy visualizer web tool using GPT-4o in under 5 minutes from their phone. The tool takes a user's date of birth, uses national life expectancy data, and renders a grid of circles where each circle represents one year — red for years already lived, green for optimal remaining years.
