Hit Diffusion Map 2025

Resources: Hit Diffusion Map

This mini project visualizes how a selection of Spotify hits spread across national charts over time, based on publicly available data. Tracks are limited to those reaching #1 on the global chart (2017–2021).

It’s a simple, static HTML/CSS/JS project using Plotly for the interactive map. I started it initially only as a way to get some experience with SQL, but eventually switched to precomputed data to work around hosting limits.
