        <h1>How Has Sugar Consumption Increased or Decreased Around the World</h1>
​
        <p>In this dataset, per capita sugar consumption was tracked over the course of 43 years in 145 countries. The Y axis represents 2004 and X axis represents 1961.<p>
        This scatterplot shows an increasing trend in the consumption of sugar.<p> <b>HOWEVER, 23 countries in the dataset DECREASED consumption.</b> <p>
        It's hard to see those countries in this form of visualization. A scatterplot using lines for each country would be preferable. <p>
        To develop the interpretation of this dataset further - I would want to:
        <ul style="list-style-type:square">
            <li>Describe how the data were collected</li>
            <li>Describe what the sources of sugar were</li>
            <li>Refine the data into increased, decreased, and stayed same.</li>
            <li>Bind the data to a geomap to tell the story of this data more clearly</li> 
        </ul>
           <p> 
​
