Become a sponsor to Jan Žák
Hi there 👋
I'm a freelance data visualization engineer, focusing on high-performance geospatial and node-link graph visualizations.
When developing using open-source libraries, we stand on the shoulders of other people, who made their code publicly available before us. I believe it’s important to keep the ball rolling, to keep improving. Fixing bugs that were left unresolved for a long time, implementing new features, or filling the gaps by creating completely new libraries.
Follow me on Twitter @zakjan for updates about my work. Feel free to contact me using any means listed at zakjan.cz.
