I built a 'life in weeks' poster generator in one HTML file

A single-file web tool that renders your entire life as a 100×52 grid of circles — one per week — and exports a print-ready PDF. Built with zero frameworks, zero backend, and zero cost, it uses a clever two-path SVG trick to draw 5,200 circles with just two DOM nodes. The PDF and SVG share the same coordinate math to stay pixel-perfect identical.
