    	<h1>Immigrants to Canada per country of origin</h1><br>
		<h3>#KnightD3 MOOC - Module 5 exercise, by RJ Weise</h3>
		<p>In May 2006 I emigrated to Canada from The Netherlands. To get a better idea of how many people immigrated from The Netherlands and from all over the world, the three graphs below represent subsets of the total  number of immigrants to Canada by country of origin for the year 2006 (and 2013 in the third).
		<br><br>
		The <strong>first graph</strong> shows the top 20 ranked countries by number of immigrants. The <strong>second graph</strong> shows The Neterlands and the three countries above and below it in ranking. The <strong>third graph</strong> shows the top 52 ranked countries (The Netherlands ranks 51 in 2006) with the number of immigrants for 2006 (x-axis) and 2013 (x-axis). Colour coding shows if the numbers have increased or decreased (see graph sub-header).
		<br>
		<br>
		Where applicable The Netherlands are highlighted in Orange (as it is my personal country of origin), and The United States of America are highlighted in blue as that is the country where I am taking the course. 
		<br><br>
		Note that after a short delay, holding the mouse over a bar of a specific country, a tooltip will show additional information.<br>
		</p>

		<h2>Comparing the number of immigrants to Canada in 2006 and 2013</h2>
		<p>This section is for the Module five assignment, in which I compare two quantitative values in a scatter-plot<br>
		  The Netherlands (orange outline) and the USA (blue outline) are highlighted in larger sizes than all other countries and the outline colours are orange and blue respectively. All countries have a purple fill colour if they increased from 2006 to 2013, and grey if they stayed the same or decreased.
