Welcome to The FanGraphs Lab, a space for experimental data visualization and exploration tools that we believe might one day have a permanent place on the site. Tools here may be in various stages of development—some use live data updated alongside the rest of FanGraphs, while others rely on frozen research-stage datasets. We encourage you to explore, experiment, and share your feedback as we continue to innovate and refine these tools.
