It shows genetic risk for multiple diseases distributed across the globe. It's easy to follow the migration path and see which diseases increase/decrease in risk along human migration paths. Click on the populations to see the relative risk of the selected disease for each population. You can pick your a disease and see which populations are more susceptible. The article is behind a paywall, but the website is free to use."
