Added new D3 chart, got Highcharts to appear but not small multiples

Still can't quite get the Higcharts to show up as small multiples as they did before, but now they just fill the window one at a time. It's not awful but it's hard to compare, the small multiples are better. Got one of my D3 charts to appear, so I may try to get the chord to appear next, can't be that much harder.
