# Adrián Maqueda

> Data journalist in Madrid. I analyze and visualize data for investigative journalism at Civio.

I'm 28 years old. I make interactive charts with D3 and Svelte, and I analyze and clean data with R, SQL, and Python. This site collects 35 projects and 69 visualizations published in Civio.es, Newtral.es, Fleet Street, and Observable, as well as personal projects.
