You can follow him on Twitter or via his blog. Social Times interviewed Pete in June about how he almost got sued by Facebook.
I’m Pete Warden and I’m obsessed with visualizing the world’s relationships. I’ve previously built graphs of Twitter conversation networks and split up the US by Facebook friendships, but it drove me crazy having to build a custom piece of software for every new map. I couldn’t find a tool out there that let me build the visualizations I wanted, so I created OpenHeatMap. It’s an open-source project to allow anyone with a spreadsheet to create an interactive, shareable online map.
I’m always excited to see other people using it, but I’ve been having a blast turning my own crazy ideas for visualizations into reality, so I want to share a few of my favorites.
