One interesting chart we've seen, originally in the NYTimes, was of Ukrainian public opinion towards Russia. As shown above, before Russia's annexation of Crimea — the peninsula in the south — Ukrainian public opinion towards Russia was overwhelmingly positive.
Respondents to surveys from the Kyiv International Institute of Sociology showed that more than 80% of Ukrainians polled had mostly positive views towards Russia. After the annexation that figure dropped dramatically, and hadn't recovered even prior to Russia's latest invasion.
Regional variation
Not every region of Ukraine feels the same. Residents of western Ukraine are a lot less likely to have a positive view of Russia (21% of respondents) than their counterparts in the east — where 53% had a positive view.
