Dissertation Survey (7 minutes)

Hi, my final university project is "All Heatmaps Are Broken". I am looking at choropleths, their pitfalls, and how we can optimise them, specifically in the context of representing uncertainty. To start I am replicating a colour scheme experiment I have read about, where they crowdsource results of people completing a number of perceptual tasks using different visualisations.
If any of you could help me out that would be fantastic! The whole thing will take ~7 minutes. Just follow this link: https://viz-test-extended.herokuapp.com/start/1. (Sorry it's a bit clunky I'm working to a deadline.. classic). Thank you so much!
