It's a great line. Would love to see slavery prohibition on this graph, as well as voting for blacks and segregation.


Rather than plot number of states versus background of #states in the union, would it not be a simpler comparison to show % of states?
I realise that for some lines this would mean they show a downward trend when support is static but the union is growing (1790-1840 and 1885-1915, roughly).
Just a thought on an alternative here.


My thought is that rather than show the number of states, show the percentage of people that live in states with changed laws. This would help with both periods of time where the union is growing (similar to AdamV's comment) as well as put things in perspective with how many people are affected (IA and VT did something vs. NY and CA doing something.)
