        <p> This chart shows WEF's 2014 Global Gender Gap Index values for a selected group of countries (The countries shown here have continuous data from 2000-2014. I hope to show change over time in future assignments). <p/>
​
        <p> Highest score = 1 (equality)<p/>
        <p> Lowest score = 0 (inequality)<p/>
