Checking models visually

In the last exercise, you found that over its history, Vanuatu (an island nation in the Pacific Ocean) sharply changed its pattern of voting on the topic of Palestinian conflict.

Let's examine this country's voting patterns more closely. Recall that the by_country_year_topic dataset contained one row for each combination of country, year, and topic. You can use that to create a plot of Vanuatu's voting, faceted by topic.
