Build A British Voter Interactive Ternary Plot by The Economist

In early 2019, The Economist built a demographic model using 90,000 individual survey responses from YouGov to calculate an individual’s probable attitude to each of three possible Brexit options: no deal, Theresa May’s deal or remaining in the EU. We presented these options using a “ternary plot”, showing our confidence that a person with given demographics would opt for any of these three choices. This let our readers survey the full landscape of support and also showed how shallow support for Mrs May’s deal seemed to be among the public.
