I agree that the drop on the graph may give impression of decrease in immigration, so thank you for your idea about scaling. I try to keep data 'as is' and give only new image of it but not new data. Scaling makes much more sense (I used it in visualization of Israel immigration because their statistic office has VERY strange approach to period slots). Regarding smooth curves, you see, the data is unchanged - you can see exact numbers in tooltips, the visualization is just new look of it, what it's supposed to be )
