I find that one helpful thing to do when watching election night coverage is to compare the results as they come in to the final (or most authoritative) poll. The networks don't really focus on that analysis; instead, they show you the swing from the last election, which is important, obvs, but not representative of where perceptions are on the night in terms of expectations of the likely result.
So I've made this Tableau tool, which allows you to look up a constituency's predicted vote shares from the second and final Yougov MRP poll alongside the 2017 General Election election results.
