200 Years of Immigration to the US Visualized

Having never been to the US and having no short-term plans to change that, I find the data itself somewhat ... not so interesting, I guess.<p>But the way the data is visualized, and the way you can explore it, is <i>awesome</i>. It&#x27;s like a database you can query just by moving the mouse around. Strike the &quot;like&quot; - that is exactly what it is.

How do you explain the last decade of your graph?<p>The totals look to drop sharply by about 70%, but looking at the data, it was pretty consistent at about 1 million a year.<p>In general I have a problem with applying smooth curves to data derived from histograms.
