Who's writing to you

 

Yan Holtz

Hi, I'm Yan Holtz 👋 — a data visualization engineer with 12+ years in data science. I've worked with research institutes like the University of Queensland and companies like Datadog, and I build educational projects such as data-to-viz.com, the Python & R Graph Galleries.

Dataviz Universe is where I distill what I learn into one practical tip a week — the kind of thing I wish someone had told me earlier.
